well seeing how this is op3 we are talking about not op2, we have no idea what is balanced and what isnt, op3 will have a different combat system than op2 thus allowing things that might be unbalanced in op2 perfectly balanced
again, the only way to tell with a new game if something is balanced is to test it, until we can do that, there is no point in argueing, just put your idea up for grabs so that it can be tested in turn, and everyone else just accept that, unless its something so out there that its not even worthy of the testers and coders time
again, argueing over something like this is pointless, neither side knows what the combat system in op3 will be like and thus put up a solid argument backed by facts
