Honestly, at this point, it doesn't matter. Those that used the TOD spreadsheets have already farmed thousands of seals. Nerfing the hunts in any way now would only serve to further handicap those that did it "legit", making it harder for them to acquire seals.

I support this idea though for future patches when there is some new currency placed in hunts. I say instead of the 3.5-4 hour respawn window for A rank and 45 min-1 hr for B rank, make it 2-6 hours for A and 30min - 2 hours for B. Also, instead of having a fixed number of spawn points, make it totally random so that the mark can spawn anywhere on the map.
