pvping with MM /TA is kinda painful. Ninja/PSN and necro/storm are good. Necro/Storm has a more varied toolbox while Ninja/PSN deals damage faster to single targets and just moves faster overall with your little zippy ninjies. Stack some stealth though and pick up grant invis. Unless you're facing a VEAT or someone else with ridiculously stacked +perc you basically look like a petless MM.
Personally I've had a blast in RV with my Thug/PSN. If I see anything less than a four person group rolling around, I don't even think about running. No buff in the game cancels -special and that alone makes it a sechse pvp set. So freakin much -special it's sick.
I wanna make an MM for RV and I'm deciding between
Ninja/TA
Necro/Storm
Ninja/PSN
Merc/PSN
or really anything that doesn't include /Dark or Thugs/
any thoughts?
