I'm in a more casual raiding guild (guild has been around a while, all good friends, some are more capable than others and it slows our progression) and we still haven't downed the last bosses - but they're in progress and should hopefully be done before this patch hits at blizzard's glacial rate of patching.
As casual as we are, we're doing a lot better than many guilds on our server who can barely get anything done in raids compared to what they were doing in WOTLK. Pug raid scene on my server went from being somewhat common to nonexistent in cata. Granted, my server (the scryers) is utterly retarded for raid progression and raiding overall...but that's just how it is for us.
I still think they're going a little overboard. The only bosses that needed tuned better were nefarian and cho'gal. At least IMO.
I'm not a big fan of having final bosses that are radically harder than the rest of a raid, like in ulduar or icc. I prefer more of the naxx/toc style where the last boss is trickier, but not so much so that it could be in a different tier of raid.
By this I mean, you gear up to a certain point to do a raid...but it's silly when the final boss is so much harder that you can't get it down til you gear up running the instance it's in into the ground and have the rest of the instance on farm. Or you're in a paramilitary style raid guild, which works for some but not for most, or you're in that mythical guild of all RL friends who are all amazing at WoW, etc.
I don't think raid completion should be limited to paramilitary style guilds who treat the game like a job. A certain amount of organization and focus is needed, obviously, but when you examine the more successful guilds those players put in part-time job like hours of raiding and probably have stricter attendance and performance measures than most of them experience AT their jobs if they have jobs.
IMO, bliz does this (make final bosses that require weeks of work for many raiders), to artificially extend the life of the raid, since they are stupid slow at releasing new content. Doesn't make it any less lame. Maybe instead of whoring out vanity pets, coming up with new ways to do x-server real id bs that nobody gives a crap about, and all the other fluff/fringe garbage they waste time on, maybe instead, they should be more focused on adding content to help justify the monthly fee.
