Disclaimer: I'm a bad player. I'm not 2000 rated, ZLO/Tagada/Nexus/etc. This suggestion doesn't come from a tournament perspective. Simply an average ladder point of view.
The one thing FAF is missing is map vetoing. Some of the maps available on the ladder pool are fantastic, and they're an absolute blast to play. On the other hand, some of them take 40+ minutes to finish a game, and the entire match is slooooooooooowww. (I'm looking at you, Vya-Protectorate)
These maps are so unenjoyable (of course this is subjective) to me to play, that I simply leave the game if I get the map. Say I have 2 hours to play FAF. If I queue up and get a game that's going to take half my time, I simply don't play it. This lowers my desire to play FAF at all. It's offputting.
I don't know if I'm alone, but with the goal of bringing more players into the FAF community, vetoing really should be an option.
I know there are players that really love the 1 hour+ slugfests (Gyle calls them "epics"). There are also players that prefer games to last 10-15 minutes. PLEASE allow players to veto a map or two, simply in the interest of having a good time. It would bring more players to the game, simply from an enjoyment standpoint. Want crazy long games? Cool, veto the 5x5 maps. Want fast-paced adrenaline games? Cool, veto the island maps.
Literally every other RTS that's currently played has this option, and it's beloved by the entire playerbase. Granted, I'm coming from a Grandmaster rank on Warcraft 3 w3c ladder, so I'm sure it's not a direct comparison, but not having map vetos literally makes me less interested in playing the game.
Of course, there are custom games. However, newer players like myself (and everyone I personally know that plays this game) simply wants to log in and queue.
