The game has had map rotation quite bad for quite some time, there are days when you only play on two maps, there is a point where I thought that they had removed maps from the game, and in fact I know that they are still there because a friend I played some of them recently.
The truth is, when they made these larger maps (about when they added City as a map for air RB too I think?) they HEAVILY reduced map variety. Currently at 10.0+ you can only see 10 or so maps. You can check this in the map ban menu now.
It seems they canceled complete the presents of maps, where one cap is closer to Red, another closer to Blue and the 3rd cap in the middle.
99% I see only one single cap, which eliminates any sense of strategy
They said they’d do this because battle is too “campy” i.e. another instance of long range vehicles being squeezed to the sidelines. Most players prefer short fast matches.
Map rotation in Ground Assault mode has been non-existent for months. You get a map you hate, so you leave, next match with another nation tank you get the same map, so you leave again, and this can go on and on for a whole hour. Maybe this is intentional by Gaijin, to discourage people from playing Ground Assault. Dunno why though. But it is certainly working in my case.
