In a lot of maps, the defending team can sprint forwards to the furthest out cover, then post there, making it impossible for the attackers to plant rallies anywhere, and effectively changing the terms of the engagement massively in favor of the defens.
This is a massive problem, especially with USSR / German maps and their god awful boundary balancing, but there’s a pretty simple temporary fix.
In the same way that defender players have a short period where they can spawn at a newly open point, and attackers have a short period before their default spawn moves forward, make it so that there is a short period at the beginning of the game where the map boundary for the defense is only very slightly forward of point.
This would encourage people to build defenses and fortifications on point, rallies behind or to the sides of (at worst) point, and allow the attackers a chance to gain useable positions.
It’s a very simple fix that would fix one of the most frustrating parts of a lot of maps (bridge battles in general, and any open maps)
