This feedback is excellent thank you for taking the time to give our game another shot after your initial difficulties. Then coming back with this detailed feedback is great for a small team. We would love to get you in our discord as we move into our steam page launch and alpha demo of chapter 1.
Regarding stalling on weaker enemies to heal this is one consideration we have had with the original press the attack resolution and skip action phase. For class's themselves in the full game we have adjusted the resolution actions to be more thematic to each class. In addition to this later enemies and encounters may have scaling mechanics or page corruptions over time. I do think for early encounters I don't mind a bit of safety and stalling but should be balanced with risk vs reward, better loot drops etc.
