So here is the DEAL
Every time you complain about getting two shot, but then you ask for tank nerfs, you are part of the problem.
They have literally gutted all tank items so that adc's and other classes couldn't get tanky, and then to make tanks viable they over loaded their kit.
You can't have a game where tanks die in 2-3 seconds and also have a game where you don't get two shot as a squishy.
Pick your battles, ask for better itemization and mastery trees.
The way the game should work is everyone should have close to no per level damage scaling on their abilities, then they should have a high power ratio. If you want damage, build it. If you want tank build it. No one gets a free pass that way. It also stops super early cheeses with high base damage abilities, because there wouldn't be any.
