Stagnation vs. Progression. The content will get stale (it'll be the exact same just higher level). And the gear is already preferable to CE weapons. It is so well itemized that even now its beyter without the higher damage cap, no one woukd use anything else. Using VoC or Fatebringer for 6 or 9 or 12 months because they are THE best weapons and keep getting upgraded is silliness. It'd get old. That's just bad business.
