Im going to call you on the daily comms grind, because its hardly anything at all. Took me a week to get both DG relics. On top of that, you can only obtain BH comms from the weekly's, so essentially after you are done with your relic "grind" (if you even want to call it that) you only need to do a full set of section-x and BH dailys ONCE a week.
I doubt the rewards are going to be required, and id say its going to be more unique looks and possibly some mounts. None of which you actually need!
This is a good way to use some systems they already have in place to offer different progression paths for different players.
