As mentioned in the video there's currently an imbalance in Terminal's first objective completion rate. The goal with all Dirty Bomb maps is to have the first objective be completed nearly every time, as we feel what keeps the maps enjoyable to play is the sense of progression rather than being stuck on the first objective all game. We believe this is a large part of what causes it's low selection rate in community tournaments.
There are three separate issues that contribute to this imbalance: the primary objective which has a few separate issues, the travel time to the objective for attackers which is effected by the secondary gas tunnel, and the layout contributing to defenders having superior positions while leaving attackers without enough options.
The location and position of the primary objective on Terminal has several issues:
The gas tunnel on objective one has long been a complaint of the community. Terminal objective one has the longest travel times from spawn to objective in the game. While in theory the gas tunnel reduces this travel time when open, in practice this often works against attackers as it's a secondary in favour of the defenders and is therefore rarely open. The capturable spawn acts partially as a band-aid to this issue by moving the spawns forward, but that can quickly be reversed, putting the attackers back to the initial spawn and at a great disadvantage.
This travel time issue will be solved by moving the spawns to the forward spawn location making it a consistent distance from the objective. The gas tunnel is no longer necessary as travel time can't be reduced further, and equally the capturable spawn is no longer required to bring attackers to the forward spawn.
The layout will be effected by any changes to the primary objective and travel times as they require specific well thought out spaces to create fun and replayable encounters. However these layout changes won't effect the themes and locations in the map. Apartments will still be on the attackers left flank, but the attackers approach will be different due to their new spawn point. The distinct tube station building will also still be there with a modified layout that works for the new C4 plant site. Attackers spawn will remain much the same, although it will have new routes to the objective.
We hope that changes to these elements (the primary objective, the travel times and the layout) will resolve the defender bias on Terminal's first objective. We look forward to sharing more with you in future!
