Welp, what can I say? I've been out-logicked here by a true genius. Win some, lose some, eh?
Have you played this game before? Just asking, because there are many obvious things that absolutely work that FDev can implement and have not. Balancing shield boosters, eliminating transfer times, buffing hull tanks, incentivized open play, etc. Simple, basic game balance or quality-of-life issues.
No.
They are profitable enough to maintain servers without adding arx to the game and breaking it in the process, or as you call it "ingame micro-transactions." At this point, it's just too big a job for them to rewrite the game I guess. Regardless, the fact that their architecture can't prevent cheating scumbags from clogging doesn't preclude them from implementing consequences. If people cry about it, let them. It will improve the immersion and gameplay quality across the board, so they'll get over it.
