Bedrock battle mode controls

I suggest with a simple action (such as Lt + Rt) switch character to battle mode. The character would no longer be able to mine and strip or sheer etc. but would open up a plethora of alternative attack moves, switch the game play into a so to speak Final Minecrafantasy. Each base character can have their preset specialty attacks. And mod creators could have their horizons expanded in making untold new attack moves
