I agree with everyone who more or less said "Moar Boldur nerfs", and think that the Kelvin one may actually be perfect; Kelvin will just have to wait until he gets to the helix that extends the duration upon a stun, before sublimate becomes the most annoying skill in the game again. In other words, it'll take away a bit of his early game, and reduce early team wipes.
