It will be good, if Blizzard will allow it. Again. Remember Wintergrasp Commendation ?
Why did they remove it from the game?
My lvl 45 restor druid has 4k honor points, lvl66 feral druid has 4k, lvl 77 warrior also has honor cap. They have nothing to buy on it. But my lvl 85 priest will be happy to get all those honor points earned by me on different characters.
