Mesmer downed bug
I wouldn’t agree with changing the Mesmer downed state “clone” appearance. In PvP, it has saved me many, many times, tricking other players in to “finishing off” one of my clones instead of me, thus allowing my Mesmer (or my team mates at least) to get back in and turn the tides.
Of course, in PvX whereby you’re all working together I can see it could be a slight issue, but if you’re properly playing as a team you could communicate to them your exact whereabouts, thus eliminating their need to guess.
Think of it from an RP or immersion point of view. If you clones are identical to you (which is what you rely on) then no one should be able to tell them apart, not even your teammates.
Agree with benhamann… Those downed clones are OP enough
