All of them combined. Joined lock outs and loot tables meant people took the easiest route to gear (the skinner box food pellet that keeps many people coming back week after week once farming bosses and paying subs).
A 25 man guild (80% of them in WotLK) can not recruit new players when the new players know that they will have an easier time in 10 mans whilst a raid is on progression.
10s aren't easier. In fact, at certain levels of progression, they're quite a bit harder. This isn't a debate I wish to get into at the moment. Check my other posts.http://us.battle.net/wow/en/forum/topic/3430936704#5
10/26/2011 01:16 PMWhen a 25 man guild can no longer run 25s they move to 10s, normally they don't split equally into 2 10 man squads.

Usually the guilds that do this stop raiding competitively. They don't usually form a superior 10m out of the remains. Now that I think about it, I've never seen a 25m guild collapse into a superior 10m.
…the average skill of a 10 man raid formed from a 25 man guild is higher than the average skill of their old 25 man raid. So even if the bosses are scaled perfectly the 10 man squad will have an easier time than their old 25 man group.
Ensidia also thought like this. Funny how quickly they switched back to 25m.

And those are the players who ran the off night raids which helped the casual players see the content, or gave them a chance to try out, and teach, new raiders how to raid, and hopefully convert them from casual to hardcore.

These raiders are using alts for raiding on off nights now… which is something that a blue poster suggested back when the equalization of 10s and 25s was announced. This is also how it tended to work in BC, with alt raids pugging some people and running them through Kara/Gruul/Mag.
In addition, if Blizz were to unlink 10 and 25m raid locks, players would have to raid both to stay competitive. 25m guilds can split up into 3 10s fairly easily to run the 10m lockouts (with alts filling gaps), but 10m guilds can't run the 25s without pugging more than half the raid.
I'm not opposed to going back to a system where one raid size is the competitive standard, and the other is purely for casuals (although this will never happen). However, simply separating the lockouts is kinda dumb. I'm also uninterested in having to kill the same encounters more than once a week in order to stay competitive. The game is repetitive and time consuming enough as it is.
If I wanted to do the same content twice a week, I would have rolled an alt. Forcing me to do it twice in order to keep up with everyone else isn't acceptable.
