Now yes I understand that for say a priest the changes do nothing. But you are a cloth class, which gets a lot of perks, there are a lot of nice looking mace, daggers, staffs, and wands even if you dont like the animations. (take into account changes to MH and one hand weapons and wait you do get perks from it)
How does this not have any use for a rogue? Rogue's can use swords, maces, and axes so they get tons of use, I know not EVERYBODY will be using em especially high end pve players but what does that matter that does not count out the benefit they get. Hunters already have this mainly because of the huge sound difference between a gun and bow, and some people (myself included) can't stand gun sounds when playing their hunter. A nice xbow is always sweet.
This is a fair change in all respects, so there honestly is no need for a change in what classes can use what weapons. A priest with a sword.... just no. Even as shadow it's not right, because most caster classes that can use a sword due so because of the title "battle-mage" and the ideals behind that.
This got a bit long, but really there is nothing particularly bad about the xmog changes. Nor anything near unfair.
