French speaking in english, sorry about that
When i said i can't defeat merc it's because the jugg in tank can't hit enough stronger to kill him, and like you said, yes we have a lot of unsnare BUT they reduce too much the damage with their shield and with the little heal, so at the end (unless the player is not good) i'm loosing, not every time but often.
All i said about merc is for the player with skill, it is obvious that the poor new merco gets screwed
