Mesmer Wv3 Help
My advice?
Stick with Berserker gear. Trait Focus and grab Feedback in a utility slot. Snipe people from range while reflecting all the projectiles. You’ll do fine and be more useful than just the ranged damage you bring.
20 points in Inspiration also gives you regen/retal on Phantasms, which is very nice both for supporting and tagging with retal.
Reflecting projectiles and retal will get you the bags you want.
Not sure what to do with the other 50 trait points. I personally don’t do a ton of Zerg stuff with my Mesmer, so all I can give you is the basics on that. I would expect 20 points in Domination is pretty standard, but I’m not positive if it’s really worth it to go deep into Illusions for shattering if you never get a chance to do so properly in large groups.
