Tanks

I honestly think that tanks have way to much power in the meta, it is absurd that a full armor Rammus can tank 10-12 turret shots and those shots do 80-300 damage to him. This is really dumb. And i know you will say that "you know that's what tanks are for" and that's fine but i feel like it is unhealthy that a that one single champion (like Rammus for example) can be so tanky and tank so many tower shots and many other things but still do the damage equivalent of a low level mage while tanking multiple tower shots. I feel like that Turrets should do % max health dmg to champions in the form of mixed damage.

Mixed damage: the damage should be changed depending on your Armor and Magic Resist stats. For example, if you have more Armor then MR the turret should do max % health damage in the form of magic damage to balance out the fact that, that said champion has more Armor than MR. and vise versa.

Please let me know what you think.

EDIT: Champions i am talking about are
