Please. longer teamfights

my god am I sick of having teamfights that last 2 seconds because the enemy Twitch is literally doing half health to the entire team with one auto, or because our Tristana decided to jump in and assassinate the entire enemy back line.

This is getting back to the point literally everybody is trying to make, PLEASE, LESS DAMAGE.

I want to be able to last longer than 0.5 seconds in a teamfight. I don't want to be forced to tunnel vision on the enemy ADC or else my whole team dies instantly.

pls rito ;_;
