Deciding what to level and play. Won't take long with 20x rates, but I figure I'd see what the realm needs. Retail Cata I played Disc/Shadow Priest, Prot Paladin, Fury Warrior. Thought about trying a hunter and a mage, but I wanna know what the realm needs.
Fair enough. What do PvE guilds on either side need.
There's always going to be a steady demand for healers and tanks, or least there generally would be room open for them, but you know what its best to look at the guild sub-section and check what classes they tend to ask for (again though most of the time they're looking for heals or tanks so yeah). Either way not much point with this topic since its not just a matter of which class is needed but more of which class can you play well so that you'd become an asset to the guild, though as much as possible I'd try to avoid plate DPS because there is a crap ton of them.
Every guild lacks intelligent players. As long as you're not mentally handicapped, and you can play your class well, you can play whatever you want and find a good guild to play with.
Warlocks are rare? Well I am set then. I was top 20 for all Heroic Firelands bosses until I quit just before 4.3. I actually never got to kill Ragnaros on live, kinda regret that.
