Hi everyone! I talked to Austin Peckenpaugh (Senior Designer) about Commandos and Mercenaries and their situation in PvP right now, and he had this to say:
I think it's fair to say that Mercenaries and Commandos have escape issues. Admittedly, they can be very hard to catch when used correctly to hug corners, but a lot of that "escapability" falls aside when attacked by multiple melee enemies, at which point they just aren't quite tough enough to sustain without further escapes. We have plans for the future that should give Mercenaries and Commandos better escapes in PvP.
Well, at least they did notice this problem. But he's overestimating how effective corner hugging is. If a single enemy applies a snare or root, corner hugging does bupkiss for a merc.
