I think there needs to be some kind of warmup time on the flag maps, sometimes the game is halfway over by the time everyone joins. :/
If the mappers just put some turrets defending the first flags, then it would force the game to start a minute or 2 later.
i have to agree with arklansman, but i think there always should be a warmup time in which you cant cap/build, maybe until there are at least 2 people in each team OR 1 minute has been passed.
