I feel like the raids are very well tuned right now. I do hope however the 'big three' bosses in heroics get harder as the expac goes on.

I definitively disagree if regular bosses get even a wee bit easier, they will just roll over. Progression is part of raiding no matter what status as a player you give yourself.
