Been using the mirage for a while now, and I've come to one simple conclusion.
Not having any movement with the dodge mechanic is beyond garbage.
Want to escape an aoe that comes in waves? Don't dodge. Try to stun.
Want to get out of a large breadth aoe? Time your dodge well, and forget about using dodge to just get outside the area.
I mean removing the movement aspect of dodge to give us...ambushes? a crappier distortion that lasts 1 second? Worth it? I don't think so.
