Q:
Which caster profession should I go with?
If you solo a lot in PvE, i’d go with the Necro.
If you group more often, chose either of the other two.
80 Ranger (3), 80 Warrior (3), 80 Thief (3)
80 Ele (2), 80 Engi (3), 80 Rev (2)
Everyone levels fairly quickly to be honest… Not sure anyone levels condiderably faster than anyone else.
That said, if you don’t do PvP Mesmer goes right out the window. You’re left with Elementalist and Necro. Necro is better at utility and survivability (in PvE, in PvP they have different means of survivability which are better or worse depending on the situation), Elementalist is better at damage.
General notes from my side:
Norn Mesmer – control and kill pvp (giant illusions make re-targeting kinda hard); not really anything special in pve exept for the chaos armor, mass quickness and warden (team support or anti caster with mass confusion – most bosses can just aa you to death making it pretty situational)
Asura Ele – great kite/distraction in pvp; massive versitility for combat style and team support for pve, amount of different one trick pony builds is insane and most of them can transition into viable “end game” builds with a few trait and skill changes.
There is too much to type about em so just youtube it (from hardcore bleed earth setups over weapon conjuration crit to 10000000000 buff builds like WoodenPotatoes runs).
Sylvari Necro – the amount of utility necros have is too kitten high! charr with McMillan hair smashing a table with a hammer also the masks look kitten on sylvari and charr, Lich form is one hell of a cannon while plague makes you unable to die for a while unless there are 10+ veterans on you (would say necros do have the most kitten if nt also the best ultis in game), can also turn into the closest thing GW2 has of a dedicated healer with Protection from Wells, Mark of Blood, Plague Signet, Signet of Undeath, Life Transfer/Transfusion, Well of Blood and Exit Death Shroud.
Btw ele have the hardest time leveling since most fall over downed if a early boss even looks at em in a weird way and have 3 times the armor a level 80 would have.
