Like for example, a sword with a fire enchant would have flames swirling around it when its drawn, or one with a frost enchant would have ice forming around it and a snowy aura. Lightning enchant=sparks flying around the blade.
I just think that would be absolutely amazing if that were in the game, it would add a great deal to the feel of enchanted weapons, instead of the regular "Oh this sword looks just like that plain one over there, and if I didnt know better I would say they were the same thing" it will be "This item used to be regular, but now i dont have a doubt that this weapon is more powerful because it has flames swirling around it" know what I mean?
