Opposite for me. I get unhinged if I'm on WoW for too long. The entire guild has basically come to the same save a few, logging on for raids, mount runs, CMs and other scheduled events only. Hell, we always have someone forget to do the WF Seal quest on reset days because they just logged on for the raid. End of expansion, so most of the content has been done and it is to be expected.
Hopefully WoD brings another good set of new things to do during farm that isn't raids. Looking forward to the CMs and possibly Ashran at least.
