It is not a bad idea to reset the perk accounts once in a while. Veteran players have accumulated so many perk points that they can flying nothing but perked planes for several tours without landing a single sortie. Sure, veteran players will earn perks a lot faster than the noobs, but at least the disparity in the piled points will not be as large. The smaller pool should be reflected in the perk costs and allow noobs an easier access to perked rides.
A full reset can frustrate new players that have to work hard to earn perks. It is perhaps better to reset and give all players a head start of X perks so they do not start from zero and can take a light-perked ride right away. In such a recurring resets setup, it is perhaps better to merge the 3 perk pools into one.
