No need to right now, imo. Just need to be able to enchant +% Damage for destruction..
We should at least be able to craft better stuff than vendor with 100 in enchanting...
Maybe we could tweak the left part of the enchanting tree to
Emproved Cloth enchant(20)
You can now improve the enchant quality on your cloth.
It could work like blacksmithing.
You can improve them to new quality up to legendary.
Regent would be 1 (or more...) soul gem
(20) Superior: 1 Petty soul
(40) Exquisite 1 Lesser
(60) Flawless 1 Common
(80) Epic: 1 Greater
(100) Legendary: 1 Grand
Improved Elemental weapon(40 or 60... whatever)
Fire / Frost / Lightning enchant deal 25% more damage (possibly staff too ? I mean... it's enchanting but we don't use staff because we cannot dual cast with them and it cost soul)
