Thanks for your detailed comments!
I appreciate your point about the two outcomes of telegraphing, I'll keep that in mind as I tweak the game further.
Regarding only having to run around and dodge since attacks are auto-targeting, that's a good point! I'll probably add more "targeting-oriented" skills in the future, e.g., by having projectiles that only fly horizontally, or at a 90 degree angle from your character, etc.
