It will be very troublesome because to progress, you have to start from MC, then BWL, AQ40, Naxx, being the progression for 40man raids. Then when your raid is nearly geared in T3 gears, or you have at least 30members in T3, you can then do the 25man raids. Then what about the remaining 10-15 raid members who aren't sufficiently geared? They get left behind? Guilds in the last 2 years were built for 40man raids, and future guilds will be built for 40man raids too. People say recruit 10 more people, which is easier said than done. Or kick 15 people out. All in all, it's a very short-sighted move by Blizzard..
