Combat value scaling is fun, isn't it?
The whole thing is kind of weird for me to be honest and something I wish was changed somehow without breaking the game (if that's even possible). I was in like 70% heroic DS gear with legendary daggers at the end of Cata, that gear had me doing more DPS at 85 than I was as a fresh 90 in greens/blues. I really do hate that feeling of becoming less powerful as you level up.
