I can't decide my next character...

Hi,

I currently have a warrior, an elementist, a monk. All lvl 20, all missions and quests done, almost all skills unlocked.

Now, I want to start over but I really... REALLY don't know which class to pick between Ranger, Necromancer and Mesmer.

I want a character that will be fun to play, that is not weak ( in PvE and PvP ), that is not rejected by the ignorants ( I don't want to wait an eternity to get a group ), and that is useful.

I tried them all a bit in pre-searing, and I still can't decide.

I hope some of you could enlighten me to the class that fit my requirements.

Thank you

Mesmer/Necromancer

my primary character is one, and I get into quite a lot of parties and do a pretty nice job in PVP.

Casting vote for ranger/necro, cursing + marksmanship = win.

Really though, if none of your current classes have mesmer secondary, and you ever want to pvp with serious builds, you'll need to unlock mesmer skills like echo and mantra of concentration eventually. There are tons of mesmer skills which seem like they were meant to support different primaries in pvp.
