Last weapon on Weapons Master TDM doesn't make sense

From a good point if view, the last weapon of Weapon Master TDM (melee) makes sense.
First, is funny have to kill the enemy using a melee weapon while the enemy uses a bullet weapon. It is for brave soldiers!
And second and most important, is fair that the players with more kills in the room get the melee weapon while the players with less kills still having bullets.
If you get the final melee weapon prove that you deserve it. Kill and defend your name in top of TAB player list!
