Suggested Change to Critical Strike: Cement the Burst > Sustained > Tank > Burst Cycle
Instead of having Critical Strikes deal double damage, what if they instead ignored a large portion of their target's armor? This way sustained DPS still betas Tanks, but can't counter-burst Assassins and targets meant to burst them since they have less armor to ignore. This would of course mean the current Armor Pen items would need to be reworked, but I think this would better balance ADCs to not just delete things come late game and actually be SUSTAINED damage that are made to melt the more durable targets, but be killed by the Assassins.
they can just change it to "Deals X% increased damage" without having to worry much.
exist for a reason. Also, in previous seasons tank items were actually attractive to pick up for other classes. If you want a solution lower damage, that way the game isn't so fast paced, which means that it isn't as snowbally.
