Returning Player - Profession Choice
Necro is the best for this because it can be made very durable with life steal and the double health bar. It is by far the most durable from the casters. While also being versitile. A heads up tough a durable build is different from the builds used in endgame content.
Well, Necromancer is pretty strong in WvW, PvP and open world stuff. For dungeons as well as raids he is not even close to being the most wanted profession there. In random/pug fractals he is good till a certain level, but all in all Necromancer is not really a group supporter compared to other professions.
GW2 has kinda just two real casters in PvE: Necromancer and Elementalist. The latter has more DPS and because of AoE heals and special spells like “Rebound” better party support, but he also is more glassy.
In GW2 there is not really a caster with good DPS, support and survivability at the same time (would be a balance breaker), so you kinda have to choose.
Staying alive via dodging and alike can be trained, but your damage und utility has a maxium. That is why I prefer to play Elementalist.
I ended up going with Necromancer. I don’t have time for raiding so random fractals and dungeons are probably the closest I’ll get to “difficult” content.
