Noticed today, daily endeavors reward 30 seals, and the time required per each, on average, did not shoot up wildly, nice!
Saw too, weekly endeavors, in an odd spot. "Complete 6 BG matches" and "Defeat 7 patrolling horrors in the imperial city districts", kind of high on time/effort required to complete them, for only 215 seals rewarded.
However the "Harvest 65 resources from the World", is curiously fairly fast to knock out, and little effort is required, and the general reduction of rewarded seals, seems aligned specifically to this weekly endeavor.
Minor suggestion [know it breaks tradition in how the devs handled this system]: Consider possibly rewarding 300 or 400+ seals for 6 BG matches or Defeat 7 patrolling horrors. And 215 or 200 seals for 65 resources.
Could do that for daily endeavors. Like the treasure trove daily felt more like a brutal weekly to me [and the weekly form of that, was horrific, that should give 1000+ seals IF you manage to finish it]. If it pops as a daily, should give tons of seals vs easy daily endeavors. 100+.
