Much to my regret I had to hear from Brian Hicks during the PAX South, that he is responsible for the removal of the broom from the Game. According to him, the broom has no actual use in the game.
The broom is essentially to the lootpool, as it resembles one of the few weapons with a combination of low damage and high range. On the other hand it is an extremely common weapon, easy to find in any household. It is accepted by most players instantaneously and people connect to it way more than using for example the pitchfork. It has the primitivitiy of a spear or shovel, but less impact damage.
So I ask you, Brian Hicks, to bring the broom back to the Community!
