I don't understand. You have a cool looking battle-axe here, how much better can it be style-wise ?Hyeah, but we still miss a battle axe, not are all "efficiency junkies" care just about "killing", sometimes we want have some style. I would be very happy if the game has a battle axe.
And to be honest, axes and chainsaws are classic weapons in all "zombie apocalypse" universe, but not in the 7D2D...
So it seems you are actually complaining about efficiency, right?
As a weapon the axe isn't the best but with enough sex-rex it seems it could hold up very well (maybe not at end-game, but there you have alternatives, many players seem to switch to ranged anyway), and the compensation for not being the best weapon is its dual-use and a saved toolbelt-slot. It looks well-balanced to me.
Maybe someone should post some hard facts about the damage and stamina values and make a real case for why it is too weak.
