Large maps are shit. Its fun when u have 30+ players but below that it shut be small for sure. There is nothing wrong with Domination and Capture the flag in my opinion. i love to play them, really.
The problem is, if you play large maps, with a small amount of people, people will go away because what you get is that there will be snipers all over the big area's and with less than 30 man it will be very annoying to play tho's maps when you get constantly get shots by snipers. When you have above 30+ people and you play larger maps, then there would be a lot of people running around witch make's it more fun for the people that love's to run and gun also. The point is: what ever you do as an admin or / server,There will be always people that would not be satisfied with what ever you do or where ever you go to as an server. You cant make everybody happy as how much we would love to. Sometime's we need to take it as it is and deal with it as it is....... even when we don't like it.
