Given that Solasta can't use 5e official feats, that was a great time for them to develop and release a set of balanced feats that are all about equivalent to +2 ASIs, but just add versatility in characters' gameplay. As many of us know, 5e's feats are...not the most balanced.

I'd actually prefer for Tactical Adventures to redesign the feat system entirely, going back to something closer to 3.5e where feats were all much weaker but you got them in addition to ASIs, but I respect TA's choice to keep things as close to 5e as possible.
