I agree that you will definitely die a lot more, I've personally not had much luck with the medium class & at the end of the third level with medium class I just kept dying.
I've found crash hopper (light class) to be the best, hardly took any damage at all at the end of third level with him, as he hits them quickly & his block move sends him flying up into the air and you can direct where he is going to land, leaving the enemies not knowing where you are.
I have to say this is the worst Ben 10 game I have played so far!
