Me, I burned out on raiding a decade ago, and never really went backagain. So Im gonna be the
wow classic gold guy that picks a race course combo for the fun, roleplay and group synergy, and thats it.
Back in the days when you tried to get advice about what class was you eventually end up with the conclusion that they all are good. Just decide which one goes with your play style, and also the race you select. Remember that in case you want to be a Shaman you HAVE to be Ally for Paladins, or Horde.
My main was a Druid, then at lvl ~26 (and about a month of playing to get there) I create a Warlock and moved to lvl 60 since WoW Classic drama was enjoyable to me. In fact you have to travel all over the world finishing quests and spending some coins (that are not as easy to come) to find that bracket, same as most of demons. (Much like today, that you hit 20 and there it is, magically in
cheap wow classic gold your mounts prepared to be summon).
Priest for sure this time. I played with a warrior back in classic and I just had five key binds. I read forums about how artists were the toughest to level never really watched videos. Though I was brand new to MMOS I never even remember how difficult it had been to level.
