I wonder if a lot of confusion/anger about balance would get resolved if some sort of FAQ post about how unit balance and maps relate to one another. For unit balance to be coherent, you need to set up a consistent frame of reference for these units to interact. For FAF, that used to just be the 1v1 pool and a few teamgame maps. Nowadays, since the matchmaker exists, you have a catalog of maps that are considered decent gameplay and can be used to talk about unit balance. across several sizes of games.
Obviously big communities for other stuff exist in custom games, but these maps spawned organically out of conditions of FAF balance and there is no real responsibility for FAF to ensure these maps stay at their current level of "enjoyability" or whatever you want to say. The maps can be adjusted to fit the balance just as the balance is adjusted to fit maps. It is unrealistic to expect unit balance to accommodate specific, niche communities in custom games.
Like this t1 bomber stuff, what is this based on? I can only assume it isn't based on anything in the matchmakers because they are pretty much always getting decent utility in games unless you just rally them into the enemy base.
This also gets into why a public vote is just stupid as well. Everybody begins using their own games as the frame of reference and working to make their map the default state rather than anything agreed upon by a larger group of people to be a healthy environment for FAF gameplay. That's why balance team is a peer selected group, same as why the matchmaker team that selects the maps is also peer selected.
