I feel as if the different skill types for different weapons, such as spears and axes are good.
though segregating Long and short types of weapon is a bit to far and adds pointless grinding into the mix.
For example. the Hammer and sledgehammer. If you are a level 8 in Short blunt, Able to reliably kill zombies in 1 or 2 shots with a Hammer, frying pan ect. If you get a Hammer that is somewhat heavier and has a longer handle, None of that training with shorter hammers applies to hammers the game defines as "long".
Beating something to death with a Blunt object that is 15 inches long should not be an entirely different skill to beating someone to death with a blunt object that is 30 inches long.
Think of it like if the Developers decided to split up shotguns and Pistols into different skills. They are different, But the end result and the way that the result of An object going into A Zombie's face at high speed is exactly the same.
Merging them back into a single skill would help saves some minor headaches with modded weapons in the future. Would a 19 inch club count as short while a 20 inch club count as long?
TL:DR Would beating something to death with a 20 inch club vs a 23 inch club really be so disconnected in transferable skills as electrical engineering and fishing?
