Hey, since you sorta handwave background feats, would you be okay with giving each character generally just a Lv 1 feat along the guidlines of Theros feats?

Aka Tough for a very tough warrior. Actor for a talented Sensate. Keen Mind for the perfect memory of a Modron. etc.

We could even establish a wishlist for such feats but the DM gives the ultimate feat for the slot, to avoid GWM/Fey-Touched/Sharpshooter shenanigans and abuses.
