Okay, yeah, I take it back I think his ultimate is balanced because it starts with only a 1-second stun and by the time you reach the final level of it you're doing teamfights, where it's not that strong altogether.

Anyhow, his cc is still relatively low-damage because of the utility. At least, low enough to push mobs rather than instantly killing him.

You've won my vote. But seeing Sla'arth has made me think even more that Khrax should have Chains I Have Broken, and it would add to the lore in imho.
