Skarner's ult now needs buffed

Skarner's ult not only does no damage(I'm pretty sure, correct me if I'm wrong), but its also on a heckalong cooldown. However, Tahm Kench's Devour's cooldown is most likely 20 seconds or less, and it can hold on to allies to save them, minions to throw them, and enemies to pull them, as Skarner's only pulls enemies. I get that to pull enemies you have to slap them three times but I think I'd rather have Tahm Kench's Devour than Skarner's ult. Slapping someone three times to pull them is a lot better than not being able to save allies or poke(obviously Skarner has poke, but he only has one, whereas Tahm Kench has two[tongue slash and Devour when using a minion/monster])
