For those who are in the beta - What would you say is the most popular class, as far as fighters/scouts/priests/mages? I'm hell bent on being a scout (probably brigand or assassin) but I don't wanna end up being Scout093 LFG!

Since there are "only" four archetypes in EQ2 it won't really matter which one you choose based on demand, there are plenty of all
However most groups require two healers when you get up in the levels some, so indirectly those will be in demand for groups is my guess.

For Beta I would just start whatever and if I don´t like it, just reroll as one of the other

In my limited observation (8 hours, currently level 7 scout), It's a good mix at the low levels. I grouped with a fighter and a mage last night and we cleaned some house. I am betting the archetypes may bottleck things a bit though at higher levels. They seem to be very specific to certain playstyles.

I think I am aiming at predator ATM... we'll see when I get there.
