At over 100 games myself, I gotta say, you hit it all on the head. Every single point is correct, and kinda sad, really. The map favors a quick lead, followed by a turtle, which is made even worse by Culling time. Stand in your spawn, and obliterate people when they start to get stacks, repeat as each Culling time happens. There is no point in being offensive and pushing. Sure, the Adrenaline spawns in the middle of the map, but that's barely worth it. All sides will have LB by the end of the match anyway, so you know at some point a Melee LB is coming toward the player with the most medals. Which, again, rewards turtling, as you can get them back ASAP to take their medals back.
