Topic: Using the elements
Using the science of the real world the elements of fire and water will actually help alot. For water think about it what happens when you combine water with electronics aka the robots? This water modual will short-out a robot taking away its ability to function. Now I know that is over powered but to babance it you can only use that modual when you are near a body of water (lake, ocean, etc) so just stay away from a body of water when your in PVP and youi will be fine. The next modual is a fire modual or a flame thrower which does very little damage to a robot however it does a great job of scorching plants and getting them out of your way.
