Um... you can self enchant to make a school of magic free to cast, with the 100 perk, make that 2 schools of magic. It just takes some serious investment to get to where the enchants equal what you find in game.
When I said you cannot enchant robes as good as the ones you can find, I was referring to that bug affecting the enchanting effect for reduce magicka cost/increase magicka regeneration speed enchantment that reduces the base magicka regen increase to 10%, which is useless. I think they accidently left off a decimal point, which will hopefully be fixed in future patch.
Enchanting seems overpowered with the 100 perk but somewhat underpowered at mid levels.
