I always thought the first logical test of FPS would be a few of the base capture troops are player manned positions.
Consider all of the unintended consequences of that. Newbie player doesn't get how to man the FPS troop and never gets to the map room. Result, 4 hours of hard work down the drain. Or, player manned FPS troop gets PO'd at the armchair generals screeching from their hovering fighters where and how to go and he slows to a crawl. Or player manned FPS troop decides he wants to run over to the airfield and spawn camp the runway, screw the capture.
Once a player and his freedom of choice and mobility is injected into the capture mechanism at such a level. The numbers of things that can go wrong, along with impacting the fun of, and sense of accomplishment expected by, the group who just expended the majority effort is exposed to an unnecessary risk. By the time you need troops to run into a map room, you basically need mindless suicidal robots. Not humans who will hesitate, worry about getting caught, or will just want to act contrary.
At the time Hitech introduces player FPS troops, I hope he introduces a different capture mechanism that will not rely on humans to replace robotic single minded purpose as the flag capture process. Like not introducing strategic objects which can be bombed to 0% effectively killing the war effort of a whole country by a single player's button press from his safe bombers at 30,000ft. Player FPS troops as part of the flag capture holds the efforts of many to the calamity or caprice of a tiny number of players. Suicidal robots are for now a fair solution.
