To me,
just feels clunky right now. He definitely needs a VU, but I think there are some inherent problems with his kit. His ult is...well, it's either too good or too bad; too good in lane, too bad (easily disrupted) in teamfights. His e is a neat idea, but I think it's sort of wasted as its own ability. W is an AS buff that while beneficial to his playstyle, really doesn't add any flavor to the champion. And his Q...it feels a little underwhelming thematically.( Oh, you scratched them EXTRA HARD? Nice one!). The biggest problem for me is that there's almost never a reason NOT to use his abilities at any time, and when you do, the advantages gained are really passive and boring.
I'm not saying that scrapping everything is the best solution here; I just think that
lacks a certain oomph that Riot likes to give champion abilities. Yi, a similar style champion, has alpha strike and meditate, both very neat, personal abilities. Mundo, a very simple champion, has a low-cd meat cleaver that really defines him.
So, yeah, I understand why you like his kit simple, but I don't think it really fits with the rest of League. Again, I don't think they should scrap everything, but I think Riot is going to take him in a direction more in-line with the rest of their champions and give him some abilities that relate to his theme better and add some extra oomph.
