Surge of the Mists was a very strong multi-utility. It did okay damage, made you evade for a very short window, interupted enemy players if hit, and could be used to engage/disengage. Great design, and not OP when you looked at the cooldown. Nerfing the ability was justified and in line with the rest of the patch I think, but the small self-root they added, kicked this ability into (almost) uselessness...
All damage was taken from CC's and that's fine. Its debatable if Surge of the Mists was really a cc, as it was more a interrupt, but sure, removing the damage was fine and seemed fair.
However: the pre-load time / self-root is just absolutely rediculous. You will never land this on enemy players in PvP if your enemy isn't a complete potato. They don't even need to dodge, merely strafing aside will do...
But of course it's a versatile skill, we have always used it (when needed) as a disengage tool as wel. Well, that's now also gone. The self-root now completely trashed the utility of disengaging, LoS'ing etc, because you see the (dis)engage comming way to easily. Is that bad? Yes it is! Isn't current philisophy that only long CC's have a obvious tells? Why did they added such a huge root/tell to something with such a low CC impact?
So how to fix? Options:
