My warsteed definitely "runs smoother" than before, in that I have a lot less rubberbanding and so on, so I am very happy about that. Also, the problems that I was having with cosmetic items being stuck at different colors also seems to be resolved, so again...yay.
My issue now is with the acceleration (for lack of a better word); I seem to have two settings...full speed ahead or slooooow crawl, there's no in between speed anymore. I'm hoping that this is only a temporary glitch because I don't always want my toons to be charging off at breakneck speeds.
