The option to extend their raid lockouts
Beyond the standard class changes that come in every major patch, 3.2 also mixes up some standards of raiding - Phoenix Dynasty Money raids will now have their own respective Heroic versions for the truly hardcore to tackle and players will also have the option to extend their raid lockouts by a week. So, if your guild is really trying to down, let us say Mimiron, you can give yourself another week to try without having to re-clear the entire dungeon again at the cost of not earning any extra gear.
