I would suggest rolling a mesmer, although I’m not too how viable different builds are after the last patch. They offer great support and utility if you run the correct builds, constant debuffs and conditions if you run the staff. In addition you have the ability to give your team mates random boons, and the elite does wonders.
I suggest you roll elementalist. It has builds that do pretty good damage, and if you use staff you can support groups and be versatile. Not only that, but you could get Bifrost and since the elementalist uses attunements, you would be using it the whole time and looking gorgeous. My ele is in full berserker gear with 110% crit damage, 55% crit chance, and 2.5k power. I run staff in wvw and hide out in the zerg while dropping heavy aoe dps pressure and raking in tons of bags. It’s squishy as hell, but I use the zerg as a meat shield.
