Rework Mauritania and Fjord for breakthrough

playing through the maps is pretty fun parat from the beginin of Siberia and the end of Mauritania.

Since the ending part for Siberia is built like a small stronghold with the walls keeping attackers out this works a good holding end game point for Push.
But now the map is being played backwards for Breakthrough, those walls only help the attackers when they have taken a point. meaing the defenders are trying to work with a fortrass that is facing the wrong way.
A simple solution would be to take the walls away and/or move them somewhere else.

Mauritania is a different story as the ziplines to the last point at the helipad is a death trap for infantry soldiers since defenders respawn points are so close to the helipad. It's nearly impossible to attack back when the enemy team is already up there waiting.
A fix for this would be pushing everything back and making the helipad area out of bounds for defenders, pushing A objective back so there is more of a warzone up there to fight on.
