First off please overlook any typos, doing this from my phone which hates me.
I (for all intents and purposes) am a new player. I played at launch and again a few years later for a couple months but its been at least two years since I've played. I have an 80 ToS and Necro neither with any AA. I have subbed so if I understand the AA bonus correctly I'll receive quite a few to spend if I level a new class instead of grinding out on my existing. Because of this I've decided to level a new toon to get the points and relearn the game.
My question is if there is a certain class which is easier to get into groups with. I have a few classes which interest me. My big four/five are the bear shaman, dark templar (or conqueror), barbarian, and herald of xotli (sp). As much as I enjoy fighters the dt/conq are intimidating only because the tank is expected to know all the pulls and strats in a game this old. Why I grouped them together since the concern is the same on both. The bs seems like a nice mix of warrior and support which I imagine would be sought after. The barb just looks fun but imagine dps exclusive slots are hard to find. Same applies to the hox though it does look like a ton of fun to play.
TLDR version: what class is most desirable at 80 for group play (pve/pvp)
