i actually don't think that its even possible to "iron man" on edifice either, just seeing how long it takes to rotate from A to B. even if you rotate through the tunnels your team will be in a relatively weak position to stop either point (ie you are REALLY far away and in the open trying to rotate to B, and rotating to A there is high ground directly overhead the tunnel, easy to have a bad uber or drop players to easy spam).
what i'm getting at here is that you're forced to choose one or the other anyway, which in my mind doesn't make for a great A/D map. the format is already random as fuck, and the last thing you want in competitive are things becoming more random.
the map is in UGC 6s this season, right? so I guess we'll see how those matches go.
