I'm not sure if WoW is something I could get back in to at this point. I just end up getting overly committed to a raid schedule and farming up the marks of the month to get the tier gear. I prefer games that aren't second jobs nowadays haha.You should try going back by yourself.
Soloing raids is a lot of fun, when if you do insane amounts of damage.
It's fun to discover ways to bypass mechanics that were built to work with many players and do it all by yourself.
I do get rather nostalgic about WoW every so often though, and I've yet to find a game that recaptures the same sense of teamwork and comradery when downing a new boss.
