Today Blizzard announced that players will just have one raid lockout per Raid Instance. Meaning you can just enter one version of a raid dungeon (10 or 25) a week, and then you choose normal or heroic difficulty for each of the bosses.
Trial of the Crusader, the previous tier raid, had 4 raid lockouts: 10 regular, 10 heroic, 25 regular, 25 heroic. And it was the Golden Age of PUG raiding.
Few guilds did all four raids, so there were always PUG raids going. They were mostly run by people who were familiar with the content, so TOC PUG raids were the odd exception to the WoW rule of know-nothing groupmates. I never partook in many (any?) but it was always a nice security blanket, knowing that I had another option if the guild collapsed or couldn’t take me some week.
ICC went down to just two raid lockouts per character (10 and 25), and now this. This change will pretty much destroy PUG raiding. New raiders won’t be able to go to slightly-stale PUG 10-mans to gear up. And already with the ICC changes you ran into the situation where experienced raiders in casual guilds can no longer put together PUG heroic raids with the experienced raiders in other casual guilds.
It will make guilds more important but I’m not sure that’s a good thing. In vanilla WoW the leader of a 40-man raiding guild was king and they nearly always acted like it. Cataclysm is not exactly a return to that, but I’m generally against anything that increases the power of guilds rather than diminishing that power.
There's also the issue of disparate raid skill. My guild has a core of hardened veterans who raid every night and know what they're doing, but we also rely on people who are far more casual or just come to raid for a month and quit. If you run tens with the other vets it doesn't seem so bad, but that'll no longer be an option, which is the kind of thing that leads to even more drama.
I’m not sure what problem this is supposed to solve. Who is harmed by PUG raiding? Who is harmed by guilds running multiple raid instances? Who suffers when I get to spend my normal raiding time doing 25’s with the guild, and one or two off-nights running 10’s with some of my more competent (and devoted) guildies?
