Then they should sell shares or something, raise commitments of an extra $10 a month, generate an on-going budget of $1k a month to fund their social media campaign. I'd happily fund $10-$20/mo for 6-months to boost the numbers.
What would Shareholders get in return? Funny you should ask. We get to weigh in on what birds, ords, etc are added to the game next. $60-$120 over 6-months to get my beloved P-61, or Japanese Raiden, or ???
$1k/mo would likely generate noticeable numbers. Then, they would need to find a way to connect these "2-weekers" with squads and trainers so they don't leave in frustration.
