Need help to pick a class for my main that will allow me to solo, group, and raid

Necromancer. Great first character, basically no gear requirements, fairly desirable for raiding, and you have multiple raid roles you can fulfill. Worst case you can use it to farm gear for your "real" main if you get bored.

Raid pulls here are probably a bit different from what you'll remember on live, and Necros can play an important part in the train-up aspect of the pull.
