This is a good starting idea. USF would finally be designed around their sole purpose which is mobility. You wouldnt have to go back to base after you made ambulance which is how usf should be and is played by a skilled player. Weapon racks is just a useless gimmick slowing usf down. Because most of the time you are forced to go back in an inconvienient time to pick up weapons or you just forget to do that and fight without them wasting a lot of your power spike.
Skilled players like who? I never use major retreat point (if youre willing to call me a skilled player). Basically every top 10 or even top 20 usf player (devm being the quintessential example), goes armor company and never techs major (no forward retreat point, which means they do end up going back to their base). I struggle to see where that claim even comes from. The fact that you claim this is how "usf should be," suggests to me that you think factions should be balanced around YOUR perception of how the game is/should be, even if game trends and the habits of top players undermine or disprove your views.
