2 Handed weapons leave you without shield, making you undefended in bad situations with only your dodge skills to rely on. They have to repay with something, and that is damage and more range.
2 handers have more damage anr arc range, making them the best choice for the one that is not to be concerned with safety or health and just wants to chop everything in his path
2 handers include axes, hammers, bows.
Bows work like normal guns, but the arrow is faste, has unlimited range good for sniping, only a wall can stop an arrow.
Axes work like normal melee weapons, and hammers are slower versions wich allways have chance to stun the target along with other status if the hammer is fiery for example
Thats what i tought of, tell if you like it
2 handed stuff would conflict with pvp classes, plus it has already been suggested and a bow with unlimited range is unfair.
