Can I have an answer? how it would hurt and why it wont help?
Special events don't use the perk system, so there would be no benefit. We never perk the planes. Or maybe I misunderstood, are you looking for more perk points to be applied in the main arena for playing special events? Why wouldn't you just stay in the MA and get points? Special events are played for the lack of MA game style, not a duplication of it.
Regarding the numbers, most special events are niche events. Snapshots, quick missions, no real order and just a night out of the MA. KOTH, head to head fights. It's not about getting more bodies, it's about having events that some people enjoy. The CMs put the events on for those who want to be there. If you want to be there, then I don't see why perks would entice you to be there. Those are Main Arena benefits for flying in the Main Arenas, to unlock Main Arena planes. Now, FSO pulling several hundred each friday, scenarios doing the same thing, that is quite a bit different than 15-20 players. Those don't need, have never needed, and will never need a perk bonus to fly in. Why is that?
