From my point of view this weapon is a good weapon on delay. For a 2 hand weapon, this is one of the fastest one you can find. From my experience, if mob runs and you starts chasing it, it is desire to have a faster weapon than a slow one. So if you are from a mini guild seldom Raid, this is a good weapon for you.
