About the PvPxp rewards
Potions are what we used to refer to as consumables use then they are gone in a very limited amount of time
Gear on the other hand is not. My opinion is that I am not adverse to gear being a reward but if so it needs to be crystal and have a very low durability rating so it is broken in a very reasonable amount of time. I also agree it needs to be bound to the person that invents it.
