Vehicle Spawns ie Flag Assets
Liberation Peak was a return to the flag asset system from BF4 (and BF1) where vehicles spawn on or near objectives when captured. In BF1, there were additional plane / tank spawns, but only from the spawn screen. 1 tank spawns at each of B and E, and there is a mobile AA at D.
Invariably one team will end up with both of these tanks, which often lead to very lopsided matches as the other team is trapped in spawn with a huge vehicle disadvantage.
It was also very easy to steal the tanks, even when the other team has captured the objective. This meant that it was often better to simply hide near the spawn, rather than contest the capture, then steal the tank, and then shoot players completely oblivious of the fact that somehow the other team has a tank. As much as it was an advantage, it was sometimes a disadvantage because now the other team can steal the tank and use it to recapture the point.
Really, these vehicles should simply spawn at base, this would ensure a more balanced game, and reduce the chances of one team having the twice as many vehicles.
I also think that vehicles should only be spawnable by the team that controls the objective. At the very least, there should be 30 s of grace period so that capturing the objective is not somehow handing a camper a free vehicle. Vehicles should also be spawnable from the spawn screen.
I don't mind the mobile AA as much, and having some asymmetrical vehicle that spawns in the middle of the map is probably okay, but 3 vehicles all in a single lane is truly bad design.
Additionally, there should not be a cooldown before vehicles respawn. Players that are driving a vehicle for more than 10s should have a 3 min cooldown before they can spawn another, so that other players have a chance to use them. I do think that this system, combined with the additional vehicles given to the team the controls certain objectives, leads to lopsided matches, it became routine for Liberation Peak to devolve halfway through into a spawn trap. This is also the case with air vehicles, as one team could have a jet, heli, and mobile AA, plus 3 AA turrets, 2 additional tanks, plus engineers with rpgs and lock on launchers, greatly reducing opportunities for counter-play. Allowing teams to always have access to vehicles helps increase the pressure pushing out of the spawn, giving the other team less time to overrun the map and set up a spawn trap.
In general, there should always be at least 2 routes out of spawn, both for infantry and vehicles, so that vehicles cannot be spawn trapped. Moving the additional tank to the spawn further tips the balance towards the team pushing out of the spawn, as destroying enemy tanks forces them to spawn further away, while losses are not a complete reset.
