Amumu and Tiamat
So I recently played a game of ARAM recently as basically Amumu Brawler and I am wondering why Tiamat and it's upgrades do not apply Amumu's passive Curse. I would love to play a brawler/support Amumu to boost my team's AP damage. I realize this is what his ult does, but I think it would be awesome and give him more build choices if Tiamat items applied curse to all hit targets. What do you guys think about this? Would that be too much?
