Coastline: While Coastline’s changes are fewer in number compared to Bank’s, they are just as impactful for players. For example, certain lines of sight from Rooftop are now blocked to prevent unfair vantage points for attackers, the Service Entrance bomb site has been moved back, and there is a destructible wall in VIP instead of a window.
The moving of bomb sites downstairs and giving VIP a destructible wall is a massive improvement for players. Rather than attackers being able to walk into Service Entrance and immediately plant in the doorway, they will now have to push between the exterior door and Reception bomb site. This allows defenders to hold the site better and prevent attackers from holding angles outside when you could plant in the doorway. Plus, VIP now having a destructible wall instead of a window gives defenders a whole new way to approach a Penthouse/Theatre defense. Personally, as a player, trying to hold Penthouse on defense consisted of hard-breach denial and intel gathering, because that’s all you could do. If you had a roamer, you would have to stay close in case attackers suddenly gained control of bomb site (which happened quite frequently since you couldn’t hold a defense anywhere besides in site). Now, defenders can expand their hold into VIP and have better mobility around the top floor. In turn, making Penthouse/Theatre a viable option for defenders.
Clubhouse: As for the changes to Clubhouse, they are the least dramatic of the map reworks. Essentially, the spawning areas Kennels and Graffiti Area are now connected with a pathway, the bomb site in Stock room is now in Bar, and there is a doorway between the bar and stage.
Connecting the Kennels and Graffiti Area spawns allows attackers to reach each side of the map quickly rather than having to repel to the roof. Further, the bomb site in Stock room being moved to Bar gives two planting sites in a small area, preventing defenders from being too spread out when holding the site. Not to mention, the doorway in Bar provides better defensive mobility to each bomb site.
