Another thing is, that many of us CANT use that weapon, because it is TWO HANDED and it is SWORD...
If you want something extra and special, why don't you create legendary sets?
I know it is a lot of work, but it would be really cool.
Yes, and it should be available only as a reward for some difficult quest series.
For example, first quest would be: Kill 50 Alliance (/horde) players. For completing this Q you would get L1 legs.
Another quest: Kill Archimonde, Kael'Thas, Illidan, etc. ...well this quests are maybe not enough difficult, but it is not such big problem to imagine difficult Q series...
This set would be nicer and stronger that T6 and not everybody, only the best players, would have it.
