Before the patch I was running Chaos/Insp/Mirage (GS/Staff) and mostly zerker gear in WvW for roaming. I was heavily relying on IH to apply vuln and do damage. Doesn't work any more. I still like this patch for on reason: The rework of Elusive Mind. 2 condies cleansed (on dodge, even with only one dodge available) actually is nice and made me confident that I can move away from Inspiration. So now I am running Dom/Duel/Mirage (GS/Sw + Focus, still zerker) for max boon removal and damage... Actually the damage feels about the same as before (on my more defensive trait setup before patch) and my defense feels actually fine, due to the over all reduced damaged. Doesn't feel too bad, tbh. Can't really compare to other classes, because I was only trying out Mesmer... But in my experience (which is not on the high end of competitiveness) Mirage isn't dead in WvW, at least for my casual roaming. I also like to go mimic + blink, which is a great disengage option to avoid being overrun by an evil horde of zerglings :D
