I'm not a main mesmer, but i like the class and would like to play it more.
I don't do sPVP or PVE at all, only WVW (because PVP in WVW >>> standingincirclesPVP).
Power mirage was not a thing in WVW even before the dodge nerf. The dmg was comparable to other similarly-geared powered classes vs single targets, but quite a lot lower in a ZvZ situation. Area dmg almost entirely came from Infinite Horizon spam, which requires dodges.
After the dodge nerf, survivability is way down (was low already), and damage is close to half, even with perfect positioning does not even make the top 10 in the DPS list now despite sacrificing all survivability for max damage.
It feels... terrible.
I will be the first to agree that dodge-stunbreak GM trait was too strong but that's all that needed addressing. If anything i'd have said mirage would be justified in having a 3rd dodge, with dodge-related traits slightly downtuned to match, as dodging is the spec-class's main mechanic.
You really can't leave mirage with 1 dodge, without compensating without e.g. doubling the effect of vigour for mirages. It just sucks. As a former game dev myself I don't like to criticise game studios for baance decisions as they're the ones with the data but this particular change seems very unwarranted.
