its pretty simply because it's aram where teamfights are happening 24/7 and those tanks just happen to have tons of aoe abilities to do damage.
Also cho and amumu both had some damage items.
Amumu went hybrid, if there were a lot of teamfights then it is obvious he would be doing a lot of damage with W and his ult since they deal decent damage, especially with an abyssal.
Amumu went Hybrid in an ARAM of course he did more damage, he probably had 21/9/0 masteries, and ap runes to boot.
Mages in my experience do some of the least amount of dammage on the team cause its usually very focused dammage on squishy targets
DoTs always end up doing the most damage in graphs.
Ok sorry all false alarm. Nothing wrong here. Hybrid tanks should be able to beat focused AD Carries and true Mages in Damage.
So from what I am seeing if you focus damage like an AD it shouldn't matter .. even a hybrid..... tank.... should also be able to out dmg everyone.
That doesn't even make sense. Even the Mages who focused AP should have a shot. But .. it is understandable if a tank can out damage even them...???? really??
Mumers has always done a fair chunk of damage, its mostly because Despair does Percentage damage, not to mention the Mumers there started building AP, which is just going to boost that damage even higher. He isn't even that tanky. Most of that Damage probably came from the Gragas and Cho. Champs with Higher Health are just going to boost the damage Mumers does per second with Despair. Pretty much saying thats a bad example of a Tank out damaging others.
amumu has always been op
