Would these be added into existing epic content?
A middle ground might be to assign each item a Rare, Uncommon, Common value, and have 3 types of scrolls drop in each area (Rare Epic Desert Scroll, Uncommon Epic Scroll of the Red Fens). So, for the really powerful items, it would still be somewhat difficult to make and acquire them, but nowhere near as bad as it is now. That is, if you're hesitant to make it too easy to make something like the Chaosblades epic.
Personally, I'd like to see optionals in epics become more worth doing, and would like some reward for multiple completions and for doing things like disabling all/most of the traps in Chains of Flame. And I'd like the emphasis on dungeon tokens to slot gear lowered a bit: 60 completions just to finish a single item is pretty exorbitant, particularly when, as I believe Junts said in another thread on the topic, epic items tend to work up to a boiling point, where you get several (or dozens) of completions, getting or two pieces for several items, and then start to make multiple pieces one after the other.
With tokens being used to buy TRs, having to wipe slots for new gear, to upgrade old epics to new versions, or due to a mistake, token accumulation tends to fall well behind epic item acquisition. I think I'm somewhere around 120 tokens in the hole just for my current unslotted epics that are a priority, and I have about a half dozen epic items just a scroll away from completion that I'd really like to slot (or have to slot in order for them to fit in my gear), and those represent almost another 200 tokens. If this is your intent for the epic system, I guess nothing will be changed, but it doesn't seem like this sort of behavior is your intent.
