What would be everyones thoughts on raids gaining difficulty levels passed heroic? So perhaps heroic, followed by heroic 2, heroic 3 and so on? This may give the high end guilds something further to work on and also add something more to achieve so that once progression into heroics is done those top end guilds (and everyone for that matter) have something more to shoot for. It could be as simple as a 2-5% buff to mobs or a 2-5% debuff to damage/healing. I personally think the buff to mobs health and damage done would be the wiser approach.
What is everyone elses opinion on this? Is it stupid or perhaps something others would like to see incorporated?
