It's way to late for blizz to do this. I don't see how this encourages players to form 25man raids. It's a cookie to the existing 25m guilds but until they make lockouts separate again nothing will change. As a 25m raider I feel i'm being forced to go 10m if i want to raid. It's a dread finding 25m guilds that aren't already falling apart .. + you'll be paying for faction change/realm transfer without any guarantee that they stay 25m. I've experienced so myself..
