Guild Wars 2

1. ‘I can move mountains!’
2. ‘Urgh, oogh, growl, SPLASH! (fully healed) – Summoned Elite Water Elemental
3. ’Klang, thud’ BAM!’ – The impact sounds of the conjured Lightning Hammer
4. ‘Behold: the ocean’s power!’
5. All previously mentioned things above me

“To do:
- Solo PvE content,
- Group world events (Dragons etc.),
- Orr events,
- Map exploration.”

You may want to consider a build which favors conjured weapons – The Lightning Hammer and Fiery Greatsword in particular.

I currently run a D/D Survival Conjurer build with good DPS outage and PvE flexibility for different the scenarios you have listed:

For maximum DPS, try the classic Glass Cannon Conjure build:

I use Berserker/Knight gear only.
