Dungeon Finder Vote Kick Changes UPDATED

Rohan points out Blizzard is changing (Patch 3.3.5) the way Vote Kick works in the random dungeon finder.  Basically the cooldown has changed so that folks who overuse this feature can't use it as often.  These is no cooldown if you don't use it often.  I am not clear how Abandon Group is going to change.

UPDATE:  WOWHead posts about this change with some idea of how the mechanics work and with their reaction.
