Trinity most of the time is a good map.
But it still has the killer fault that most of the other maps do.
Despite it's size, it forces entire teams through very narrow channels. So instead of spreading the players out like a 512 map should be able to, it STILL concentrates them in only two or maybe three places.
The size of the map matters less than the layout of the fields. When fields are spaced widely, it forces people into the shortest routes. IMO, no field should be more than 25miles away from it's neighbors, UNLESS for some specific strategic reason(i.e. HQ airbases)
