Every. Single. Individual time. Anything that isn't a heavy tank finds a bush in that corner. And they Will. Not. Move.
They will not advance to get LoS on targets. They will not spot. They will not shoot. They will sit there until their tracks rust over, the sun grows to envelop the earth, and the black hole at the center of our galaxy finally swallows all of creation as we now it.
I know asking people to actually play the game they queued up for on purpose is a bit much to ask in -most- World of Tanks games these days but Pilsen seems to be a particularly egregious offender.
I don't really know as to the exact reason why, but I'm strongly convinced it has to do with the TD hills and all the brush on the 0 line. While you -can- play around on the mounds and hills in the middle, they don't provide good advancement lines. Even vehicles with good gun depression struggle to get good lines of fire, and on the other side of the rails the dip is too deep to provide good shots for anyone in the middle. Then, once you're out there you're sort of stuck if anyone is up on the hills at C and its counterpart in the south, as any attempt to reposition is highly likely to cost you some serious hitpoints. Then with all the brush on the 0 line you can get extremely close to a vehicle without spotting it, meaning trying to push up is a big dice roll unless -everyone- comes with you.
Honestly? Flatten the mound between 9 and 0 and then shorten the hills in the north and south to only give slight elevation, then reduce the amount of brush on the 0 line by about 50% at least. It'd open up the side of the map for more movement and decrease the sheer threat of the tank destroyers at the back. Make people use the terrain and flank by making it a good option.
OR, and this one is spicy, raise the 0 line to be the highest traversable elevation point in the map, remove almost all brush, and add some rocks and machinery for cover. This would drastically change the way the map plays out but I'd say thats a good thing.
