La7 or Spit16 factories just adds one big porking target.
Splitting the MA into several arenas ... no ... fracturing the community is bad for business.
Perks and Attaboys are having a lot of impact on player behavior. Even though vets don't care about such things, it is what guides the newer players. And with the Quake mindset so prevalent spending perks is kind of pointless since people will go out of their way to HO or ram your expensive ride.
Early War planes put a higher premium on manoever. You don't have lots and lots of cannon, you don't have quick acceleration or a wide range of top speeds. Energy tactics still work, of course, but a lot of the garbage that goes on now in the MA just doesn't work as well with EW planes, so hopefully players would change their tactics. And carry those lessons to late war planes.
RPS will not address the Quake mentality as it pertains to porking, hording, etc. - that requires changes to the underlying mechanisms of the MA.
There will be a lot of whining about RPS. "I pay to fly a P51 and now you won't let me" ... and so on. If, however, RPS was rolled out with a handful of new Early War planes (P39, Ki-43, MiG-3, B-25) so that there was more of a rationale for the change, that could help.
In the end, though, it depends on if HT thinks RPS was a "success" in WB or not.
I think RPS could help things in the MA, but in and of itself it's not a cure-all.
