Since the last update it is necessary to raise the melee weapon before hitting with it. This is really annoying, especially regarding the fact that you have always to change weapon when you meet some zombies - it is one of the most used control situations in the game and after 100th of times it has no entertainment-character any more.

Additionally it is annoying that, when you put the melee weapon on your back again, your primary weapon / fist are still raised.
