Really, this is some wonderfull customer service. You. Get. To. Kill. Your. Dev. Talk about motivation to not piss people off.
I can imagine WoW will follow soon. After all, they have this knack on making stuff like this more polished. Maybe support will provide home adress? Or maybe they will simply "put down" responsible dev at players request? Next gen MMOS will propably include this in basic package.
(lame joke disclaimer: sorry, could not resist to twist this.)
