I have tried the mod with my friends. It's funny at the beginning.
Then, they don't want to play it anymore. Since the battle mode is difficult to use.
If you find a mob in a cave, you shouldn't like to still need to change to battle mode after finding your weapon.

I hope the main hand item change to weapon automatically when player use battle mode. And the mouse wheel is used to change weapons. Or it changes to battle mode automatically when player use weapon.

Please speed up all animation time, like attacking, dodge. Or something can be speeding up animation time, like attack speed.

Sorry for my poor English. It isn't my mother language.
