Need help with mesmer
The most common pvp spec is shatter 4/4/0/0/6. Gs/staff, the staff can be changed to sword/x for WwW or duels. Shatter is a really fun spec to play, I recommend it. I never really liked phantasm specs, relying on ai isn’t my thing, so I can’t help you on that.
If you’re on EU and need help to get into dungeons, pm me.
PU is still popular (4/4/6/0/0). I am fond of playing with CI lockdown (4/4/6/0/0). CI and Shatter are both harder builds to play in pvp because you are glassy.
