You can't even attempt to help losing lanes with the game in this state
Fix the amount of damage going around.
I went from Gold III to Diamond with 62% win rate as Udyr at the start of the season, decayed to Platinum III, and now I'm something like 1-12 with Udyr, because it's become impossible to carry or influence games.
If one of my lanes is losing, I'm likely going to die in 2-3 seconds if I attempt to help it, because damage is so absurdly high, and the enemy is going to snowball out of control whether I help or not.
