I mean you're right they could. Why do you think they will? Just curious.
I'd much prefer a root attached to the knockback than have it cleanse movement impairing effects, but that's me.
I could possibly see them adding in new set bonuses when the expansion comes out.
However, how many merc/commando players are going to hang around for that if in the up coming patches our issues, and other pvp issues in general, are not addressed by the devs?
Bump for Justice!
