[RPG] Is two-weapon fighting only as a full-round action balanced versus fighting with a two-handed weapon

balancepathfinder-1e

One of the players in a Pathfinder game in which I am playing is arguing that characters should be able to get the additional attack for fighting with two weapons when attacking as a standard action, instead of a full-round action which is normally required to get additional attacks.

He argues that a character that dual wields a longsword and a shortsword with Two-Weapon Fighting and Improved Two-Weapon Fighting is a decent amount worse than a character that wields a greatsword and has Power Attack and Vital Strike.

Full Argument:

Two weapon Joe
Point buy (ultimate min max 15 point buy)
Lvl 11 (so he can get most of the twf feat chain)
15 dex +2 race +2 levels = 19 (twf req)
15 str
Feats TWF, Improved TWF, Greater TWF (and some others but these are the important)

Weapons +2 Flaming Frost Longsword, +2 flaming Frost short sword (note this is almost all of the chars WBL)

BAB +11 +2 str +2 weapon = +15, so Standard action TWF +13 (-2 twf)/+13 (-2 twf)/+8 (additional -5 ImpTWF)/+3 (additional -10 Great TWF)

Assuming all hit (not very likely) dmg 1d8+2 str +2 weapon +1d6 fire, 1d6 frost, 1d6+1 str (+same modifiers) x3

Average dmg 4.5+10.5 +13 physical frost +14(4×3.5) +14(4×3.5) fire. Total:56 combined dmg/round

Two handed bob
Lvl 11
16 str +2 race +2 level: total 20
and still has 5 points to spread around to other stats
Feats: power attack, Vital stike, Improved Vital stike
Weapon +2 Flaming frost Greatsword (still has tons of wealth left over for other stuff)
BAB: 11+5str+2weapon= +18 to hit. Standard attack vital Strike power attack: +15 (-3 pow attack).
Damage: 6d6+7 str +9 power attack +2 weapon +1d6 frost +1d6 fire
Average: 39 physical +3.5 fire +3.5 frost Total = 46 combined dmg

Analysis:
Total Average twf with standard: 56 combined
Total Average two weapon: 46 dmg.

Adding dr 5 and elemental resistance (not that uncommon at level 11)
TWF now deals: 8 damage
Two handed deals: 33 still and he has 32000gp extra to boost his combat effectiveness

I'm personally of the opinion that this restriction is in the game for some reason, especially since it survived the transition from 3.5 to Pathfinder, but I can't really wrap my head around the reason.

Ignoring the potential to slow down the game with additional attacks and looking strictly at balance, is two-weapon fighting only as a full-round action instead of as part as a standard attack action really balanced versus fighting with a two-handed weapon?

To clarify after reading AceCalhoon post. I was only calculating adding my house rule to allow the standard action additional TWF attacks. to allow a TWF to have mobility and keep up with damage roughly to a Two handed fighter. So that is why I didn't include the itterative attacks from BAB

Best Answer

The TWF fighter does less damage than a two-handed fighter on a single attack action (about 35% less), but virtually ties with a full attack action. Letting the TWF fighter always get his full attack damage significantly unbalances the equation in the other direction.

The thing is, whichever configuration you take, you can work on infinitely twinking it out. Two-weapon fighting is better when you want many more attacks. Being a rogue with sneak attack is the number one example of this. Or if you bleed per attack (like with Bloody Assault). Or use poison. Or use the various critical effects from the critical feats. Or want to use some of those attacks for trip/disarm/sunder attacks. There's a bunch of ways to increase your TWF damage by stacking "per hit" things on top.

Two-handed is better when something has DR or you're only getting one attack action in. Per-attack damage plusses and minuses and additional conditions affect a two-weapon fighter much more than a two-handed fighter - a "bard bonus" is multiplied in value by number of attacks. And as you note, you have to get a full attack to get those other attacks... But that's the same thing with a L11 two-handed fighter, they lose out on a lot of attacks when they can't stick and hit.

A straight fighter will do more dps in an abstract sense with a two-handed weapon than two-weapon fighting, if all he does is straightforward hitting without any other interesting feats. But if you change the TWF rules, your player is just going to turn around and layer the other TWF twinks on top and suddenly it's the more powerful thing, and you have to start worrying about your two-hander player... Because he who inflicts the most damage wins the game, apparently.

Also, there's a difference between optimization and real play. Real adventurers find gear, they don't "have 32000 to spend on it." I've played and GMed a lot of Pathfinder, and players have run and enjoyed two-weapon characters as much as two-hander characters. (Sword and board, however, sucks.)

Since the peanut gallery demands "math," here's some reasonably maxed out L11 characters, using all the Paizoey goodness. Each has more special abilites than one can reasonably enumerate, but I tried to stick to "jack up the numbers" options as much as possible. Full builds are below, but the relevant stuff here is that:

  • 2HGuy, attack action: +23 (4d6+29/19-20 plus 1d6 fire plus 1d6 cold) 19-20 x2 - power attack, overhand chop is giving double STR to damage, vital strike, furious focus
  • 2HGuy full attack: +23/+15/+10 (2d6+25/19-20 plus 1d6 fire plus 1d6 cold, 2d6+29 for attacks 2 and 3 from backswing) 19-20 x2
  • 2WFGuy, attack action: +15 (1d6+15/17-20 plus 1d6 fire)/+15 (1d6+12/17-20 plus 1d6 cold) 17-20 x2 - two attacks from Doublestrike, piranha strike is like Power Attack for Dex, if he hits with both then 1d10+1 rend, if he crits +2d6 bleed, agile weapon enhancement gives +dex to damage
  • 2WFGuy, full attack: +17/+12/+7 (1d6+17/17-20 plus 1d6 fire)/+17/+12/+7 (1d6+14/17-20 plus 1d6 cold) 17-20 x2, if he hits with both then 1d10+(1.5x Strength modifier) rend, if he crits +2d6 bleed, agile weapon enhancement gives +dex to damage, +2/+2 during full attack from twin blades, and also +4 AC bonus from two-weapon defense and defensive flurry)

Versus let's say AC 25, the average DPS (including crits and rend) for each is:

  • 2HGuy, attack action: 55.67 (plus maybe shaken)
  • 2HGuy, full attack: 87.06 (plus almost guaranteed shaken)
  • 2WFGuy, attack action: 35.55 (plus two points of bleed)
  • 2WFGuy, full attack: 81.80 (plus 5 points of bleed ongoing)

So yes obviously, in high mobility situations the 2WF guy loses out (though he does get two attacks, not one, from his archetype), but he's pretty much neck and neck in a full attack situation, any slight change to any of these numbers makes the winner of the full attack follies go back and forth. Both these characters have loads of other fun stuff to do, they have more feats than they know what to do with. The TWF guys is obviously much tighter on feats and stuff. Keep in mind this is a straight fighter compare, and there's other ways to fill out TWF and all those rogues with sneak attack can stack a lot of damage on... Go look at some build guides and there's plenty of L11 twf builds out there that do a lot more than this.

Does the TWF guy lose? Yes. But the question is, "is the answer to let him have his 81-point full attack with a standard action?" The answer to that is no, it unbalances it back the other way.

Full builds

Because everyone has stat boost items I usually don't add them, but in this case I decided to make up the wealth differential caused by the weapons with a +4 belt of strength.
