I disagree on that partly. Some maps, yes, they boil down to center/left/right flanks. But Grain Elevator is eminently defensible, if the Russians know what they're doing. Likewise each building in Trainyard is practically a fortress. Same story with several control points on Barracks. Same story with Commisars and a couple other levels. The map that has no real strong points (and that gets played WAY too much) is Spartanovka. That's where it comes down purely to flanking.
The problem with the maps comes in when the teams don't play the objectives. Like on Grain Elevator (pre-patch) the Germans would flank aallll the way around and attack the elevator before there were even objectives there to capture. Which divides the Russian's attention, causing them to lose the forward control points, which makes the Grain Elevator the center of the battle....and two squads of Germans are already on the top floor murdering people who are respawning.
Or on Spartanovka, when the Russians get pushed back from the church, 90% of the team would camp in the City Hall building and snipe, practically giving the Germans the next two control points for free.
When both teams play like teams the game is awesome. You get the joy of defending and the joy of assaulting. But when teams basically fracture into 20+ people playing lone wolf, shit sucks just like every other modern FPS. (Guys behind your lines, turning corners into people who light you up, that kind of crap.)
I honestly really enjoyed the game, it was just the lack of a strong presence from the community that made me stop playing it. So I'll be stopping by this weekend, probably. Honestly if they've done work on making sure the protected spawn areas and such are sensible now, that'll do a great deal to cut down on the lack of team play and the consequences for it.
The only change that has me going waaaaahhh? is the machinegun buff. It needed to be MORE deadly at range? I was rapeing people using single shots on Pavlov's with the MG months ago, sniping basically the entire length of the map.
