Its........ An interesting concept for his rework. The Q being a channel is funky to me however, they should revert that. I do not know of any channel that you move in.
The slow on the W is interesting as well. It probably should not be that harsh, but it should be there i think.
The passive is more able to be utilized, and especially with the E + W combo. So thats good.
The E att speed boost i find was better than the minor armor reduction.
The ulti, if it still damages structures (which i cant remember if it does), was made better by giving it a slow that builds up.
EDIT:
Just remembered about Vlad, but his W isnt canceled if he is knocked or cced pretty much in any way.
