I really don't know where to start with the whole 3.2 Patch. Everything that I hear about it seems to be good. I'm sorry, but if there's somebody that's whining about Emblems of Conquest being handed out in Heroics (and all the lower raids) and Emblems of Triumph being handed out through Daily Quests... well... what did you expect? You're obviously Hard Core... and better than all of us (see whut I did thar)... and you'll get your upgraded epics way before the rest of us. So, simmer down, clown.
But one of the best things for casual guilds is the ability to extend raid lock out times. Honestly... one of the best things ever. Take our casual guild now. We run once per week, and generally about 3 hours. It's enough to clear Ulduar's first 4 bosses. And that's about it. There's no way we'd be able to clear Naxx in that amount of time. But in two weeks, completely possible. On our schedule, we'd be "clearing" Ulduar forever and still never see progression in. (Well.. we can skip bosses, but that's not the point.)
The hardcore people still get to be hardcore, but it really opens up some of the deeper parts of raid instances to more casual players. Great move, Blizzard. I wish I would have thought about this myself. (And if I wasn't lazy, I'd dig up the link where I did think this up, 'cause I'm 95% sure I posted about it. I'm 100% sure I've thought that it should have been done before now.)
