From a pure ##s perspective, there is no incentive to up a perk ride of any kind, ever, period.
If you win you get very few perks, if you lose, you lose big.
If the house averages were like this in Vegas, it would be a ghost town.
So once you accept that, and accept that anytime you roll in a perk ride of any kind.
That your doing it for the "Fun Factor" that you don't "Care" if you lose perks.
Because your doing it for the fun.
Then you maybe poorer in perks, but you will be happier.
Also accept that upping any perk ride is the same as pinning a "kick me" sign on your back.
Its a red flag to a bull, You will be the primary target even in a host of others until your dead.
Embrace it, Accept it.
The perk system is there to add diversity, to let certain planes & vehicles be used on a limited basis.
That makes them big fun to kill.
