I agree that it would make it more appealing. I think the thing with the mode is to treat it as a map rotation map. So instead of 10 flags (like a lot of hosts like to set it at) set it low to 3-6 flags. Also put a time limit cap (I like 30 minutes). So if you cant cap enough flags then time will eventually run out.
It does become frustrating when you get base camped. But I think that's what actually makes the game mode somewhat fun. The thrill of pushing the enemy back! Reminds me a lot of domination from Modern Warfare 2 lmao
