I normally dont use mercs though -_-. Pvm or Pvp zon?

She is an old 09 PvM zon that I built about 4 years ago. The merc really helps her, especially now that he has reached a fairly high level. I don't know if a merc would do any good for PvP.

Since the zon is tweaked for MF, she needs the merc to run interference. I just want to tweak his gear and see what works best.
