The good thing about this map is that it easily tells you who's a noob or an idiot: just find out who's not wiring/ blocking bridge, which is helped by seeing which part of your half is lost to the enemy.
There's surprisingly a lot of people that can't figure out blocking a bridge in any meaningful way to prevent a rush.
From what you say, there is few noobs or idiots, that's relieve me.
I played the map yesterday, don't like it, not because it is in auto-match, just because its brainless and yes I don't really understand the "why" for creation for this map. Same if many people likes it.
The map is badly design from my point of view, not because of the bridges but the configuration around the bridges, there is nothing to hold them if you take the initiative to rush it and take it. The map isn't make to play but to wait till the countdown ends.
All 3 bridges could have been indestructible.
Side Bridge heads could have been design to favor attackers and not defenders.
