I recently left retail cause I was mostly tired of it and the atmosphere around retail end-game. I havent played this expansion however since I was 9. Never really fully got into the game back then but I figured it would be a really nice nostalgia to replay the game for its story and hopes to meet the casual friendly community on the way. I really want something favored around solo play and smaller groups to start, not super concerned for raiding just yet/if at all. Im very torn on what to play. Im trying to get the best idea of the classes or atleast advice about leveling and lvl 80 solo content if anyone wants to provide. My top choices are hunter, warlock, and druid but Im having trouble deciding just because I know how long leveling can take and I dont want to get to a really high level and realize I dont like the class.
warlock is def the best, MM hunter will make a boost to the top when ICC hits too.
Druids are also sitting in a nice spot, but the first two I mentioned are better options for you. Both of them are solo classes and good for group content.
@Yaytibbers Thank you. My next 2 trains of thought for that are ease of play and look of character. I like transmog a lot. Which do you think is easier to play and also would look the best 
lock is EXTREMELY easy, never any downtime if you go aff… so much leech with the spec you never have to stop, with a hunter you’ll have to drink every little bit until you get viper, even then you might still drink some.
I did Aff in original WoTLK Arena Tournament. Yes it is good and in battlegrounds too. In WPvP though, many warriors, most DKSs, shamans in ele hunters in Surv, rogues and boomkins will eat you up though.
