The first of the refinements being made is that we're combining all raid sizes and difficulties into a single lockout. Unlike today, 10- and 25-player modes of a single raid will share the same lockout. You can defeat each raid boss once per week per character. In other words, if you wanted to do both a 10- and 25-person raid in a single week, you’d need to do so on two different characters. Normal versus Heroic mode will be chosen on a per-boss basis in Cataclysm raids, the same way it works in Icecrown Citadel. Obviously the raid lockout change doesn't apply in pure Icecrown terms though, as this change goes hand-in-hand with a few other changes to raid progression in Cataclysm.
what the hell... this change is gamebreaking, my guild has 3 raid days and on the off-days we used to do 10-mans which i really enjoy.
the post also says 10 and 25 mans will drop the exact same loot, this will make 25 mans completely obsolete! Why would you go with 25 players when you can go with 10 aswell. 25 is just alot more messy -.-
english is not my native language and so i simply lack the vocabulary to express myself properly but i really really do not like this change.
