2 week trial accounts, TA/DA only.
Pay for play, first 3 month's Early war arena the only one open to him.
Unless they can manage a better than 1-1 kill ratio. Then unlock.
Next 2 months let them play in Midwar.
If they havn't learned the basics by then they never will. So turn em loose & pray.
The real advantage to this system is they'd actually learn to fight.
No endless runs in la7's or HO everything in sight in nik.
They'd have to learn to cope with the early war planeset with all its limitations.
Then they can move up a step to midwar. More plane options, still no late war monsters. Still more lessions on actually learning to fight.
Plus the influx of all the new players into one area would make a very target rich enviorment.
And, it would teach them to work together to stay alive, to not kill steal.
