Guild Wars 2

I like pve, pvp is fun also, i do not have a preference, i like both caster and melee.

Hello, i am a level 80 warrior in GW2. I am close to finishing him soon, i only need two more ascended pieces to finish my build.
I was wondering what would be the best class to start leveling.
My thoughts are :
- Guardian – suitable because i already have heavy armor full ascended gear.
- Elementalist – I like participating in community organized events, like Wurm and Tequatl, and i like feeling usefull. Elementalists might stack in DPS and reflect eggs at wurm.
- Engineer – Condition damage. Nah, warrior can condi aswell.

I am stuck on Guardian/ Ele, what do you guys think? Do you think that leveling a new class and start making a new set of gear? or stick with guardian and reuse my actual one. Start leveling a maybe more “fun” class ?
