Blizzard has announced some major changes to raiding for Cataclysm and it's great news for ten man raiding. Details found at this link http://blue.mmo-champion.com/t/24401856405/cataclysm-raid-progression-refinements/
Ten man raiders aren't second class citizens any longer. Ten man raids aren't where 25 man guilds pick up extra emblems and feel special for crushing content they over gear. Details aren't set it in stone of course, but it appears people will be able to choose the size raid they want based on their preference alone.
Like I said it's great news for ten man strict raiders, which I'm not because pugging 25 man ICC is easy and has a separate raid lockout. Most 25 man raiders are screaming, kicking and crying their way to shelter to avoid the falling sky aimed square at their crotches. This means 25 man raiding is dead, they won't be able to pick extra badges, and of course Blizzard can't possibly make 10 man and 25 man raiding content equal in difficulty. Then again, I don't know where I would be without the six extra frost badges I have picked in my 25 man ICC runs.
It would seem if anything that the QQ flood shows there is plenty of interest in 25 man raiding out there. That's hard to see through the tears though, maybe when they dry the kids will see it's going to be okay, that Blizzard will find a way to make sure people who undertake the challenge of adding 15 more people to a raid still feel like their special and better than people who don't. That's all.
