I'm able to COMPLETE those things within the week, then they restart on the reset to be COMPLETED again. So that isn't really the same. When I beat the NF/raid I get the rewards on completion. Imagine if you beat these things, then had to wait until the reset/armsday to receive your rewards. Or let's say you beat Golgoroth, but have to wait until next week to fight the next boss. That's a much more accurate analogy.
