errr u do know if u stand too close to a person u can be targetted even in hide? also r u sure its not just mage T-stroming u rather then targetting u in hide?
I'm quite sure lol, there's other features to this 'bug' but rogues are the only ones who really suffer from it in siege
it's like if I downloaded something so that thunderstorms never hit me, I'd imagine mages would be rather ticked off but no one is bringing this problem to public eye so I'm trying to without saying too much D:
it's also hard to prove unless you can get them to target you while you have them targeted and pop in and out of hide/vanish, which I have and have a bit of video. Even people I never thought to do such a thing I caught by accident

(support ticket, no accusations allowed on forums)
^completely different issue from OP anyways (unless it's linked but I highly doubt it)
