Yay! Managed to play a relatively lagless full round! First time on Flood Zone. Map is a hot mess to learn but I like it. It's the right size, I think, thanks to the play space made up by all the interiors and side streets. I look forward to playing more of it, and properly learning the layout.
Tried a Shanghai game three times and each and every time the game crashed, forcing me to task manager out of Battlefield 4.
Had an Operation Locker round, managed to finish it. It's Metro 2.0. I can see that they've attempted to mix it up with the outdoor areas, but they've missed the point of what made Metro a grind. Alternate paths don't mean shit when all those alternate paths are still bottlenecks towards the same areas. And that's what Locker is: bottlenecks. You've just got more of them than before. Maybe it plays a lot better with 32 players.
Really keen to have a proper go of Golmud Railway, Hainan Resort, and Rogue Transmission, since these seem to be the bigger maps. Hopefully they don't disappoint. It would suck if I ended up falling back on Caspian and Firestorm once the Second Assault expansion pack rolls around, for my big map fix.
No idea how Dawnbreaker plays. Haven't even seen the layout.
