There shouldn\'t be enchanted weapons at all.
1) If they will be made common, people will whine that weapons have too large power. If they will be made rare, power-levelers will be the only ones to have them and pretty much will rule the fighting side of the game.
2) Looking at the tabletop games; Those which eliminated (or highly reduced) possibility of coming across such weapons, usually have stronger role-play base than those which made them quite common.
3) Fancy weapons most likely will take attention away from various non-fighting jobs, as if insinuating that fighting is the main point of the game (Well either that or we\'ll have Thunder Pick Axe of Gold Finding, Frosty Leash of Groffel Training, Fire Hammer of Sword Smithing, etc - which would make sense, since who says only weapons should be enchanted? But it would make things ridiculous none the less).
