Let me point out, as others probably have.
LEVELING DOESNT TEACH SOMEONE HOW TO PLAY THEIR CLASS
I raid heroics. Currently 7/14. I have been a heroic raider since it was released in Ulduar. I have been playing since TBC. Do you know what I did when I first hit 70 and started gearing for raiding as a prot pally? I stacked spellpower cause I heard it was a good stat for Prot Pallies. It wasn't until I failed in raids that I only needed a SP weapon, and I should be stacking tank stats. Leveling as a prot pally didnt teach me that.
You all bitch about the 90 boost saying ti ruined LFR. Guess you conveniently forgot how bad LFR was before the boost. Only difference is now you have something specific you can blame I guess.
