There's an interesting bug if you try to request for your Epic Weapon when your inventory is full (tested on mid, but i guess the behaviour is the same on the other realms).
If you try to ask for another weapon from the king and if your inventory doesn't contain any space left, it will automatically put the weapon on the floor, and then you should be able to get all the available epic weapons for your class. For example, as a hunter i'm currently getting the bow / sword 1h / sword 2h. just for testing purpose of course
Hope it can helps.
Thanks for your great work and support.
