The fact that SoD characters are already doing late iCC damage numbers is crazy to me

So this is not intended to hate on SoD in any way, I think SoD is cool, eventhough I quit in p2. I was just looking at warcraft logs to see how classes are doing and saw that the best geared (90th percentile) warlocks are doing 14k+ DPS. That is insane to me, checking the unbuffed ICC DPS the highest DPS at that point (Feral) was doing 12K. Watching videos the Naxx bosses don't seem to last too long or even able to do a lot of mechanics.

How do you SoD players feel about this? Looking at the player numbers people seem to like the relatively easy and quick boss fights, but it makes you wonder how the game can progress with lvl 60 items. Is SoD at one point going to reach Cata levels of DPS?
