League-of-legends – When is split-pushing/backdooring a good option

Sadly, there's no sure-fire way of resolving this situation.

You won't be able to rely on minions to take out their towers and nexus, especially if their uber status gets to the point where they can start defending their respawning inhibitors. If you get really lucky and get their nexus towers down, you could just farm minions hard enough for yours to take the nexus down a bit then try to dive the nexus. I'd consider this a Hail Mary more than anything else, though.

If you know you're going up against a team that is going to steamroll you once they get maxxed out (2+ carries), the main goal is to take advantage of the fact that they will be weaker in the early game. If you zone the carries and/or kill them enough to keep them from getting geared and leveled, your team will get powerful enough to take their nexus before they can do anything about it.

Assuming you find yourself in that unfortunate position anyway and forcing their team to split up isn't working, you absolutely have to focus the primary damage dealers down first. If they stick together and you're not killing their carries first, you'll take way more damage than you will deal out over the course of the fight and you're sure to lose.

Usually during the Mid/Late game both teams are roaming/securing objectives so the only times you really should go for Farm or "Cs" would be when there are no objectives or when there is a large enemy creep wave pushing against your inner towers. If your trying to attain important items before a big fight and the lanes are pushed out, jungle camps are gone or the fight is about to start i recommend just buying wards or potting up (buying the red/blue/green/oracle elixers).

You would also want to push waves out when objectives on the map are coming up like blue/red buffs. Keeping track of their timers would be very useful. For example: You have timed when dragon spawns at 17:58. Your team then pushed out some waves at top/bot/mid at 17:30 and forces one of the enemy team members to defend. You can then easily secure the objective. If the enemy does decide though to confront you it will be a 4v5 situation and you should always mainly come out on top of the situation. If it this is done to your team you would want to send your most mobile/easy wave clear champions to defend these

Timers for objectives: Starting timers (when they spawn for the first time in the game) blue/red buffs - 1:50 wolf/wraiths/double golems - 1:40 Baron buff - 15:00

After death timers (time till they spawn again after deaths) blue/red buffs - 5:00 mins after death wolf/wraiths/double golems - 50 seconds Dragon camp - 6mins after death Baron - 7 mins after death

I hope this was helpful for you.
