terraria
So, I was playing Terraria, just created a new character for 1.3 because my old character was a bit cheated and I didn't have fun with it, couple hours after, I make a Hellevator, then notice that the ceiling is really low, or the lava is really high, so here is my question, is that a new feature in 1.3 or is it just an unlucky generation ? How am I suppose to fight the wall of flesh like that ? Btw, my world size is Large.
Find a place where below you there's a lot of ground (ash) and hellstone (no buildings or anything where the imps can spawn on). Dig a tunnel (width 2) under you (block fireballs with a fast pickaxe) and mine until there are no visible places to spawn for imps, other than your own tunnel (which you can even fill with dirt).
Then it's easy to mine hellstone while blocking the fireballs of the few imps with your pickaxe (always face the enemy while mining). There won't be many imps since they don't have much space to spawn.
A stack of potions, magic mirror and any flail (for worms) should then be enough.
(I think the tunnel in the image is too wide, but hopefully this still makes it more clear)
There are several problems with hell and several ways to overcome them.
Hellstone
Lava

As far as I know and can find, there haven't been any changes to Underworld (Hell) generation in 1.3 or since (or even before for that matter). There aren't any changes listed in the 1.3 changelog or Underworld wiki page. (There's new music though.)
To me, your Underworld ceiling looks maybe a bit low, but nothing out of the ordinary, and the lava seems normal. I find that parts of the ceiling often is touching the buildings (Ruined Houses, to be exact). I'd say it's just some unlucky random generation that made it out a bit cramped like that.
As for fighting the Wall of Flesh, you can always level some sections of the Underworld to make it easier to fight (make flat platforms, etc.). Hopefully there are some suitable areas in your Underworld for that.
