(Responding to Degritone's response here)

Except... it is longer. Much longer. Skarner's ulti lasts for 1.75 seconds. Jarvan's lasts for 3.5. But with Skarner's, there are items (i.e. Merc. Scim, Mikael's) that can cleanse it, and with Jarvan's, having any sort of dash or teleport makes the cataclysm escapable. Here, though, it is 100% impossible to escape. Rito talks all the time about counterplay when they're designing champions--Kalista is taken down by targeted cc, Jinx by high mobility, Sivir by long range, Kog'Maw in the early game, to name some adc's as an example. Here, though, it's 100% impossible to escape him and just by walking around really fast (he does gain 75% of target's movement speed) he can effectively suppress all members of the enemy team at once... I find the thought dreadful to play against.

And for the record, gaining 75% movement speed is the equivalent of stealing 37.5% movement speed. For comparison, Stalker's Blade smite steals 20%, BotRK steals 15%, and Malphite's Q steals 26% at rank 5. Might wanna tone that one down a bit so we're not zooming around at 700 movement speed permanently.
