I have better idea! Resub 10 years from now:
+many more content avaiable
+you dont even have do LFR, you can SOLO stuff! perfect for causal players!
+flying, flying everywhere!
+there is even possibility that WoW will be B2P till then
and most important, we don't have to see you for very long time! (because you leave forum also, right? it's not very causal to whine about game that you're not playing on fansites)
