I think it's issue is more in how it works and how latency plays a part. it's like a movement tool not a warpy tool (for want of a better term) so you can quite literally be dragged through ground aoes or even off platforms in some arenas where parts of the floor get removed. you try and rescue a player over that gap and they just die..

if it was more of a warp to healer rather than a move to healer i think a lot of the issues would be fixed
