Guild Wars 2

Hi, after taking a long break from GW2, I’m playing again, and this time I want to main Ele (or mesmer or necro), so I was wondering in lieu of the recent changes what the best sort of build for the different game areas is.

Since I’m looking for a new guild I’ve only really just tried spvp since returning. The Celestial amulet stats seem quite strong now, but is it worth it obtaining ascended celestial armor/weapons?

And as for builds I’m not sure. I tired out the semi classic 0/0/2/6/6 defensive ebuild with strength runes and celestial and it seems incredibly strong in spvp, very hard to kill, while still doing lots of pbAoE DPS. Is this the best build right now or is the S/D fresh air build that was popular when I left still good?

And a final question, are any of the new GM traits viable?

fresh air is pretty good for dmg still but garbage in team fights. other popular builds are 4/0/0/4/6 or u could even do 2/0/0/6/6
