"But 3 perks for a cost? People are talking like 3 points on a plane will suddenly kill a plane and make P-51s or stuff inaccessible to the general public. I don't think that's true. 50~200 perks may kill motivation, but 3 points is just enough to boost motivational qualities and promote a more careful line of flying, but not high enough to feel punitive when the plane is lost."
If 3 perks is such a nit ... then why perk it at all. I fail to believe that a 3 perk cost will motivate anybody to make another choice. If a perk cost does not really cause a "pause" when deciding what to fly, then don't perk it at all.
Also, I don't believe that we need to motivate people to be more "carefull" ... the arena is already filled with pilots that won't engage unless they have a tremendous advantage and if they miss on the engagement, they extend .... all the way home.
Instead of burning all our brain cells trying to figure out ways to make people fly different aircraft, we should be thinking of and promoting ways to encourage fights.
