I kiiiind of agree, but also, I think it sort of misses the real issue here. The real issue is that there simply isn't enough content that makes full use of a set of BiS gear. You can participate in the parsing game, or you can do ultimates, and that's fine. But the reason why it feels like everything gets synced down is because that's really all there is once you hit BiS. Some more content designed for people at max ilvl in any given patch would be nice. Personally, I'd enjoy some 4-person content that is tuned to that level of gear and skill.
