I reported this back in beta, and multiple times in game since launch. So I’m rather shocked that such a bug still persists two weeks into the live game. I certainly didn’t expect the first bug fix to be Signet of Illusions :p
Using the Skill #2, Deception, while underwater causes the Mesmer to be immobilized. So he can’t swim for the surface anymore. Considering there is an sPvP match which utilizes underwater combat this should really be a priority.
Better yet, how about giving us a real ‘drowning’ state like every other profession has, instead of just a copy and paste? :-) I realize we’re the last profession introduced, but that’s really no excuse.
