Not really excited at all for a new map. First and foremost imo is to get War-party's. A map that will need as much teamwork as Fortress, I shudder to think what Pugs/randoms even accomplish in such a thing. Rather let us group up now. Also with 20v20 these maps already seems like alot of empty space with a random chance of seeing another player. gonna need that player count increased.
No, remember the trailer where the Blood Angel Captain was assaulting a Chaos held structure and at the end were ambushed by the Tyranids? That area IS the Fortress.
I heard that when the Fortress comes out they'll increase the player cap to 32v32, though depending on the size of the map it might be small :/ Also they have to release War Parties before or when the map comes out or soon after at least, it's gonna be a bit hard to coordinate an assault like that.
Well, if you're fine playing with random players in BF's conquest maps, you'll be fine here too. Yes war parties are needed to make the map fun and fair for both sides, but not to the extent that the map won't be playable due to not having it. Beside, you're an Ork, Orkz need no coordination They will use the many of the assets, but I doubt that it will be the exact replica. Given all of the current maps are completely new.
