Sorry for the late response.
A tutorial would be useful, having the option to check the hotkeys at any point could be useful also.
AGI will always be a problem I feel. The other stats feel like they don't add much or are situational, while you will always need speed no matter the playstyle. Thats why I suggest to try the game without having it as an upgradeable stat. Maybe have it increase as a unlockable perk for the dino and other fast classes.
From the two battles I got, I feel that once a character is being focused, there is no way to save it. For example, I felt that healing was not worth it. You would spend one wait and one cast to heal one hit worth of damage which might not be enough to save wounded from getting ganged.
I hope the playthrough was useful. It is always fun to try this game.
