Yea its totally assassins doing too much damage
Let's just ignore the fact that practically EVERYmeta tank item has damage strapped to it.
Titanic Hydra:Bonus Health, Bonus AD, Bonus health regen, an auto attack reset that scales damage with your MAX HP. DeadMans plate: movement speed, armor, health, Bonus magic damage on hit that slows your target
SunfireCape:Health, Armor, an Aura that does AOE magic damage a second
Abysal Mask:Health, Magic resist,Mana, 15% bonus magic damage to nearby targets
IceBorn gaunt:Mana,Armor,CDR, Bonus on hit sheen damage that slows you
Of course, all the meta runes for tanks also give damage!
Aftershock Grants massive bonus armor and MR, then deals AOE damage after a delay.
Grasp %maxHP bonus damage to target that also heals you and raises your max HP, effectively scaling the rune every time you use it.
Chrysalis Start the game with a very low amount of bonus HP. After 4 kills Get AD or AP Adaptive
But yea, god forbid the glass cannons get any damage from their itemization! It's the end of the world!!!!!
