1) With sentient weapons, devs have introduced a mechanism that can make unequipped BtCoE weapons BtA. (Apply Jewel, remove Jewel).
2) I like BtA stuff.
Now that we have this precedent - perhaps you can observe it a bit to see if it creates any problems - I think it would be great to have a universal method that can be used for all kinds of BtCoE items - not only ml20 weapons.
I wouldn't mind if it's DDO store only. Perhaps similarly priced as sentience toolkits.
