This comment is solely made for 2v2 players as I'm not a 1v1 player.
I honestly wonder if any of the more serious 2v2 players here think that emplacements are really ok.
Take the maps Kharkov or Crossing in the Woods for example.
I'd say that in regards to these maps the real issue is, they are in 2v2 map poll.
Crossing is fine for 1s, but its way too small for 2s, didn't creator itself stated that the map is not intended for anything besides 1s somewhere?
Pretty much the same for kharkov, way too narrow, always devolves into indirect fire fest, because map structure completely prevents any flanking attempts in 2s unless you pushed one of opponents already.
Some maps just aren't suited for 2v2, but we have to play on them regardless.
These two make Pripyat river look appealing as 2v2 option.
