We'll have to see it in action, and even then we might arrive at different conclusions. There's a lot of factors at play - map layout, player counts, how easy/hard it is to secure your stockpile. But I read what you just wrote, and I'm chomping at the bit, as if you're trying to talk me into liking it, not the other way around.
Even with a team of four, it's easy to see a breakdown of having one player focus on defense, two flag runners and sending a spoiler over to the other team to prevent scoring.
The way it was described in some of the write ups made it sound less of a clusterfuck and more of a game that unfolded over a quick series two-part rounds. Flags get snagged pretty quickly, and then it's a matter of keeping them in place, for both sides; the top half of the round is about securing, the second half defending. And each half is only 30 seconds long.
We'll see. One week from today, actually.
