The placement of Sandbags around the Heavy MG's (The one second floor, building behind D, and the one covering B from the right) has made it, very, very hard to take them out. Most, if not all of the grenades people try to throw into the one next to A bounce back and team-kill. Meanwhile, the MG mows down the troops that used to flank from B, into A to clear the buildings and other side of the wall. You can't get in through the stairs behind the blighter, 'cause there's usually another MG or an SMG guy covering his ass!
The MG covering D is now harder to take out from the front (flanking, I know, would solve it, but it's not easily done in some cases) as the sandbags block shots through the wall, and, unfortunatly, the guy on the MG is BEHIND the wall, but still able to fire on troops, without putting himself in harms way. And due to the nature of HMG's, the guy on it just sprays through smoke without a care in the world. Large issue, the building the MG is in has Spawn Protection over half of it, so there's really only one way in to flank it.
They contribute to alot of greif on that map (as the allies), epsecially on the first two cap zones.
