I think the mindset a lot of people has is (the only reason I would even think about having it) would be if you shot some dudes 262 down, and started receiving some nasty PM's, you can just give the guy his stupid perks back. Keep him from whining any more and upping a spit 16 for another 2 months to get another one. (I've shot down 262s and have had people in a 'rage' tell me how they got their perks)
