Half the vehicles that you may spawn are ground based, the other half are aircraft. That’s how you get to 50-50 (in theory).
As I mentioned, things skewed toward GFs in practice because GFs are given better costs and are favored mechanically.
Similar efforts have been tried before…and all of them resulted in negative effects for teams (notably ODL).
It’s best to not interfere with players’ freedom of choice at all…let them spawn what they wish and let them/the enemy team sort it out in combat.
I didn’t say you’d be successful, I said you could try to bargain with the others. (Ultimately, their choice is theirs anyway.)
Beyond that, there’s little to be said except that efforts here to control players’ choices are an effort to affect thousands of players.
Not really…the main mover of tickets (outside Battle) is traditionally the capture zones. More often than not, one side will best the other via tickets than via TDM. In Battle, the avenue to winning varies between these.
What role aircraft have in all of this is…“limited” to put it flatly. Kills are about the only direct means they have to influencing tickets (100 tickets/kill)…a measly sum in the grand scheme.
