The problem i see is that Kindred Seals are the worst of the "seals" to obtain. At low levels you're going to get Beastmen Seals, at mid to high levels you'll get a mixture of Beastmen and Kindred Seals, at high levels you'll be getting Kindred Crests.
There is no real way to farm just Kindred Seals. I did a lot of leveling back at the lvl 75 cap and have very few Kindred Seals to show for it.
No matter how you look at it, farming for Seals (of any kind) is far from efficient, players with the ability to do KSNMs will dry up quickly, leaving these items extremely difficult to obtain.
