Fixed a couple of things, as indicated by the change log. Mostly nerfs to his passive and ultimate and reducing W's duration while still allowing you to have more than one at a time in a Pain Link "net".

I'm suprised none of you found the most broken part of his kit. Assuming the previously unspecified projectile speed of the pulse wasn't insanely low, it would permastun an enemy unit if it is only connected to a Pillar of Woe and the distance between them isn't too high.

Anyway, this concept was mostly an experiment with his Q and E, plus W for extra effects. The passive and ultimate are mostly just random abilities that fit thematically. My next concept will probably be the usual "way too complex to exist in LoL" stuff.
