welll it's not like people who use double big swords really have any other option of gameplay besides spam single slash. The big swords are MEANT to have superior stats because of the inability to block. When you put the glad code on and people can't flip big sword users, it gives them an advantage.
Or, if the glad code isn't on and people can flip them/use ice or lightning element they're more of a fair fight. It's a balance issue and I stand by the fact that using big swords/ double bigswords isn't gladiator, it's just spam but still technically a melee weapon.
