I'm saying the troop transport role in this game is to capture towns. In that role you don't mix it with "supply other GVs" or what-have-you. From a gameplay standpoint, if you're running goons that should be it. We're already blurring this line since you can load troops AND the rockets on the sides, but so be it.
IMO if you have troops you shouldn't be screwing around doing other things. You've made your mind up what you are going to do, you know what you have to do. So from a gameplay standpoint (how they are used in this game, how they work) I think muddying the waters does nothing to help, and possibly only leaves open the way to game the game or find hidden exploits.
