I am okay with honor capsules being something rare, but quite honestly I don't even care when I get them because they are so underwhelming. I get far more key frags and BE from playing. I get key frags all the time when i login each day and the BE amount is tiny. It would be nice if something interesting was added in instead of just key frags and BE. Maybe some OE, or something remotely useful.
If they really are trying to reward you for good behavior, shouldn't it actually be a reward?
