Also, I'm not sure about any other characters but they totally screwed up Yuki (IMO). I can no longer Teleport -> Any other skill. I could probably work around it (Yuki ezpz) but it was such a staple of her PvP that I don't know if I wanna bother =/ I'm not sure what else they changed about her because I only played one match.
AdamantZ - Level 75 Sieg
Reotheria - Level 70 Yuki
