Easy fix for damage being too high.

Nerf anything that mitigates armor and magic resist so adcs and assassins have to work to kill tanks. They'll still be able to dive squishes just fine.

#yes pls!

Its not that easy, for some champs +5 is a lot more than for other champs, better make a armor/mr per level increase. Also damage in early is ok, it's the late game that's problematic. I would say decrease the damage multiplier by a bit.

reduce penetration options and damage goes down immensely tbh

Wouldn't do much. I'd like to see what the game would be like with a flat 15 percent reduction or so across the board.

The only thing is I'm pretty sure that will make ADCs and sustained damage dealers even more powerful.
