I agree, 12-16 player servers are perfect, but hard to find.
edit: well, didn't read the "per team"...
Well the less the numbers the more personal the game is. I like a bit more numbers so you don't get absolute suprise losses in structures. Besides that, I prefer 8-16 players a team for sure. At least you can keep track of the 6 guys in field 4 guys repairing 4 guys in tunnel and 2 snipers. Any more than that and you start getting over-bulk hard-to-affect sort of things, where your tossing rocks at brick walls at best.
Thanks thats the spirit...I a old scool too...I am of to find your server....
