the failure rate of 25 mans belongs solely in blizzards hands.. if 25 mans are falling apart because of lack of success that means they are to hard and take to long to learn for your average players.. want more 25 mans.. give them the tools or the ability to have more success while raiding them.. cutting players and dropping to 10 is due to the other players not being able to handle the raid... so guilds cut the worst players and focus on the best 10-12.. .. time to start nerfing till you see more success. use to be the first bosses were simple and it got harder as you went in... now.. its hard from the outset and gets hader still as you go in.. sorry.. but new players dont have 7 years of raiding experience to adapt..
