Arcadian Knight
Spending more design resources and still less frequently usable than the cantrips like the very fun Mage Hand or the first level spell .... claiming ff is boring while ignoring the other possibilities familiars provide like having it do some scouting and similar things yeh sure... like so many maneuvers have anything approaching that versatility or frequency of use.Which equals half of your fights, or as I said, multiple times a day. Note if you get the fighting style too it is twice between short rests.
If the owl was somehow killed every fight then you might still have it once every short rest that DM is being an **** if that is the case.
Sorry you are in my opinion blowing smoke.
