This is a lol-troll post, right? Well, this can't be taken seriously anyway. But still ...
So you want them to be of SoO difficulty and scaled up every expansion? Well, then Blizzard should just remove the old raids, 'cause it will be IMPOSSIBLE to find 40 people to do an outdated raid, that drops shit loot. At least now, few of the people still go to MC and BWL, if they make them as hard as they were in their prime days, noone would go there.
I still do BT every week for Warglaive Main-hand, and if by any IDIOTIC retarded chance they make it require 25 people to clear it, I wouldn't bother, fuck, I would just delete the Off-hand because I know I'll never be able to go back and get the Main-hand.
