Game balance was centered around all of an epic sphere becoming available at level 20, we didn't see any decent gear sets to replace level 15/17 Sharn sets. (assuming the player has run a few EPLs)
The U51 Revamp states monsters will be reduced as well, but I suspect that won't be sufficient for many epic characters in their heroic gear.
So, to that end, will we be able to expect Epic gear that scales in the epic levels, beside the level 29 gear?
We'll be experiencing a dramatic shift in capability and it's the height of folly to call it "Epic Levels" when everyone is forced the trudge through them in "heroic" gear. (Because sets are a thing and there are no low level epic sets.)
