So what do you suggest?
I suggest that the time delay between smoke and hit should be constant. I think it would be good from design point of view to make the time delay different for each ability which would give balanceteam another tool in their toolbox for the future. But if balance team cant be bothered to do that I would happily take the same delay on all airstrike abilities compared to live version for the sake of consistency.
I am not 1v1 pro so someone should correct my numbers but going by my gut feeling:
PTAB strike: 6 sec delay
Ost cluster-bomb strike: 5 sec
Soviet Airborne Rocket strike: 5 sec
Soviet machine gun strafe: 2.5 sec
USF machine gun strafe: 3 sec
Ost smoke screen strike: 2.5 sec
OKW smoke screen strike: 3 sec
Tell me if I forgot anything
If all strikes would share one delay I would make it 5 sec.
As for how to as for how to achieve it, I would suggest to make it so aircraft spawn in accordance with targeted spawn point, not on the edge of the map. If that would make aircraft spawn in the middle of the map sometimes, so be it, its the price I would be willing to pay.
