I didn't really look at the gear changes before update 19, I was following the enhancement discussions.
I have a number of Bound to Account, heroic base items. These come from quests like Sentinals of Stormreach and Delera's.
The ones that have at least +11 in stacking enchantments now say "Epic" and do 2[w] damage. There's also an intermediate step I've seen (around +9?) called Paragon that does 1.5[w]
This is exciting to me, because this means I can level up my heroic BTA base items through epic levels (some recipes are still useful) and manage my overloaded bank space.
Before I get too excited, I just wanted to check if this is WAI? If this was announced by the Devs, I would really appreciate a link to the announcement so I could confirm it for myself.
