Yep, you can lose Personnel as a seperate lose based on performance, whereas Wealth is only lost as the fee. So you could attack someone for -2 W and -4 P, but then also lose -10 P based on your performance.

That's more a consequence than an action that can be taken. 

I stand by my underlying opinion. Give the core aspect of the RP, the Wealth metric alone suffices as the expense for actions. The Personnel metric as supply doesn't seem to contribute anything to game state.
