As long as you are controlling the movement I don't think you'll have any problems. Some CRs are better than others for PvP so if you don't have a good one that is as fine tuned as it can be some players might just think you're a bad player, but there are so many of them out there that's not out of the norm. I've used Enyo in Ashran a few times and I don't think anyone ever picked up on it. I certainly wasn't dominating in there, but it did what I needed it to.
