Here's a current frustration of mine, and a suggestion for a solution...
I'm not very good at this game, partly because I'm not particularly good at video games in general, and because I developed bad habits specifically with SupCom, as I wasn't aware of FAF, only played Vanilla, and got addicted to being able to pause the game and treat it like a turn-based game. I have at various times forced myself to play against human opponents but quickly got consistently beaten by low ranked players, resulting in a sub-zero rating and enough frustration to cause me to put the game down many times.
Recently I've started playing again, and while I don't think I'll ever be able to play according to the widely-agreed upon META, I have changed a few things that I do so that I can play more strategically... so that I can focus more on growth of my economy, my production, and my tech level, and focus less on where my tanks are. I've been playing against DilliDalli and M27 and have developed a way of playing that has resulted in more success than I've ever had against those AIs, and that I've developed muscle memory for, to the point where I no longer need to pause the game in the first couple of minutes to keep up with the requirements of setting things up properly. I feel as though I have a better understanding of the true nature of the game and what is required in order to improve and be more successful, and now I would like to start playing human opponents again.
Problem is, that I've been sitting here waiting for the Matchmaker to give me a game for the last 3 hours. This isn't a fault of the Matchmaker - this is the fault of my -45 1v1 rating. People who have been as bad as me usually don't stick around for continued punishment and frustration, and rightly so, players who are better than me don't want to waste their time playing someone with a -45 rating.
This isn't a complaint about the Matchmaker - I am happy to keep waiting for a game - but I do have a suggestion that might help people in my situation - allow AI to be an opponent for very low rated players so they have a chance to demonstrate that they have improved. I won't be able to reliably get matched unless my rating increases, and I can't increase my rating without getting matched. There should be some sort of "release valve" at the bottom of the 1v1 ladder to help returning players who feel they have improved to resurrect their ratings, and maybe one of the better AI mods could serve as this release valve.
