Well, I think you wrong... The problem of adding 25-32 is small maps... and as long as this server is NODOWNLOAD servee, it won't be a good option... It means that on the rush hours, there will be 32 players on Oasis - this is crazy.
You need to think not only on how many time you wait for connect, but also how it will be fun to play with a much much more players on those small maps...
