A lot of folks sit around waiting for a Caphras event to make the swap between DR and Evasion (or the other way around).
Why not just make coupons for it? Release them as rewards during events or make them purchaseable on the Pearl Shop. Seems pretty win-win to me.
Example: Use on Bheg's Gloves (TET or higher) - receive Leebur's Gloves at the same enhancement level.
