I don't think there should be a max limit on maps, just a minimum limit (Mainly for large maps). I know you can get some very fun games on ATCS with 30 people.
This reminds me of a server in 2009 where it once had 92/96 players on the server, atcs. That was fkin buggy just moving around the alien base, soo many fkin rants and goons. Building was soo annoying simply because other aliens blocked you.
Also, when humans work in teams of 10, they generally win. You can't really get 10 tyrants, marauders and dragoons alltogether to rush a human base, thats what alien's have being doing in 1.1 constantly, which is why aliens win. If they never rushed, and just did what humans do, human's would win. Humans just need some sort of slow health regen so hit-and-run won't work terribly good. (I hope it doesn't appear like korx's, the normal tyrant from gpp heals slower than a human without a biokit in korx in terms of percent/second.)
