I’ve noticed that during Face Off and Capture games held on the two winter maps (I forget their names, I think it’s Temples and Snowblind), it’s possible for a team to camp right outside of the respawn point and completely bottle up the other team. This arises from the fact that both exit points are visible from the same place. It’s made worse by the fact that one of the two exits in each mode is a Varelsi spawn point as well.
It doesn’t happen every game, but when it does it makes for an extremely NPE game. It doesn’t seem like it would be too complex to simply push the shield back a little further (in particular on Snowblind) so the other team can’t sit right outside of the exit and shoot you on your way down to the ground, or to make it so the incoming BB start at ground level, instead of having a 1-2 second fall before they can melee.
