I'm a little torn here. On the one hand, I don't think it's wrong to have a PVP mode where the main objective is a non-player target, as the mode is player VERSUS player, not player KILLING player, so as long as it's still a competition it's a PVP mode, and can function as a change of pace over doing nothing but constant team deathmatch forever.

On the other hand? As a healer I kinda wish I had more to do when ice spawned other than spam repose on physical DPS.
