I've been relying heavily on cantrips rather than frequent rests. The problem for me is that once-per-rest abilities don't seem more likely to hit (or hit significantly harder) than unlimited-use ones. Missing with your once a day "big gun" when your stats and positioning are as favorable as you could make them is just not fun. Perhaps once crafting is added, there will be +accuracy food or potions that will help the player feel a little more in control?
