I personally love pet battles, but it seems that I'm just about the only one. Queues last forever. There's little resources out there covering it, and just in general everyone I talk to in game doesn't really care for it.
I just started playing again after a 2 year break and everything is fun. Cata seems like it was a subpar xpac but I'm still having fun and can't wait for MoP content. About pet battles though, can someone a bit more experienced than me shed some light on the state of pet battles in WoW? I'm curious if i'll continue to have fun if I pursue it further, or if I will inevitably end up in a place all by myself with nothing to do.
