It is all in the application, my friend. If I make a field before my character and keep pushing it forward as I walk, I've got a shield, allowing my sword wielder to wildly charge into battle. I can convert Thermal to kinetic as well, and use any heat source to launch my character through the air. I can put it on the ground and simply have the field change the direction of the energy, as long as the output is the same as the input. So I can make my opponents misstep, and instead of dodging, they step directly into my blade, or conversely, I can jump onto the field and it'll take the downward momentum and shove me forward with the same force, giving me a faster than normal speed....

Yeah, it can be pretty lame, but when we talk about teamwork to get objectives done, I picture my character filling more of a support role, allowing the rest of you guys to be pretty crazy in your methods. Meh. We'll see.
