I stopped raiding about a month into Cata because i was obsessed with arena. I then quit a couple of months after and i'm wondering if its worth coming back for Firelands! So any opinions on the new tier would be awesome.
not only for firelands but also for the new arena season with new gear to obtain so can be, worth coming back more if your guild you were in when you quit hasn't removed you orr will accept you back in quickly and get you raiding.
If your friend still play then yeah you could kill time with them. If not then no its boring all by your self dailys will be dailys and raiding is Meh.
Just my opinion.
