Not sure how time poor you are, but I have friends who log on after their kids goes to sleep and play from about 8 - 11pm.

WoW Forever is way more casual than Retail will ever be. As long as you're in the level range of dungeons, and you have the proper dungeon setup (1 tank, 1 healer, 3 dps) people will let you join their group. (so don't try a level 45-52 dungeon when you're level 15).

Raiding is a whole other thing that I've never done in Classic. Only in Retail. As I understand it, the 2 are very different, but still pretty sweaty.

Me and my friends are playing the Beta right now. I play by myself sometimes and I can pretty easily come across people who will help me. (unless it's a quest where you have to collect quest objectives based RNG. No one will help because of how collecting RNG quest objectives works in groups).

Anyway, I'm really liking WoW Forever. Buy a sub when it comes out on Nov 4 (well maybe not day of. it's gonna be a shit launch day as usual).
