I discovered a nice build for my ele to use in dungeons with a staff - 20 fire, 20 air, 30 water:
- Spell Slinger (3 stacks of might from cantrips) + Pyromancers Alacrity (20% faster fire spell regen).
- Quick Glyphs + Inscription air perks (20% faster and double boons from Glyph of Elemental Harmony)
- Aquamancers Alacrity + Cantrip Mastery + Soothing disruption - Water weapon skills + Cantrips recharge 20% faster, Vigor + Regeneration from Cantrips.
Skills to equip - Glyph of Elemental Harmony, Mist Form, Armor of Earth, and either Cleansing Fire or arcane shield if needed. I use Avatar of Melandru for my elite in dungeons.
How to use:
1) Each cantrip gives you 3 stacks of might, 1 regeneration, 1 vigor (more damage and health + endurance regen).
2) Glyph of Elemental Harmony gives 2 stacks of might in fire attunement, or 20s of regeneration in water attunement on a 20s recharge.
3) Water heals, Fire AoEs, and Cantrips recharge 20% faster, Water blast should do a high amount of splash healing on melees near your target.
4) Swap between fire and water to drop down damage and heals on recharge. You also deal Pbaoe damage when attuning to fire, though its not much, and healing ripple when attuning to Water along with permanent health regen ticks from soothing mist and near permanent regeneration from the Air magic perks.
5) Click on Cleansing Fire after attuning to fire for the triple might stack, regeneration and vigor, and drop down your AoEs. Save Mist Form and Armor of Earth for emergency moments, these now become godly 'Oh ****' buttons, save your life a lot and give you regeneration + vigor too.
5) If you die jump to a waypoint, swap to Air attunement, use glyph for a 20s swiftness to get back, though you should no longer be dying anywhere near as much now with this build.
6) Ideally you want Power + Vitality + Healing gear, though I'm not sure where to get this or if it exists yet (Priory armor is precision + vitality + healing which is just a completely terrible combo). You get a significant damage boost from all the stacks of might you can get through the perks so there shouldnt be any DPS problems here.
7) Use Glyph + 20s Regeneration while in water attunement along with the soothing mist passive for much higher survivability (regens health astonishingly fast for 20s).
Yummy, healy, nukey + far less squishy dungeon ele.
Had some amazing wvw battles and 100% another zone, got a much better feal for the Necro and generally had the best time I have had in game yet 
Regretting playing Azura a little as they don't show off the gear that well, oh well
