I really hope SE gives us a NPC that will allow us to shave off augments, even if it came with a fee or quest item as payment. Anything to allow us to try again til we get what we want without having to re-buy or re-craft for that item.
Currently the only way to do this is with gear that can be stored in sets, traded to NPC for slip, and when reobtained will revert back to their original stats.
