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?
That is one of my big issues with d20 games in general because the way they implement just makes the probability issues of a flat-curve that much more aggravating. But it has carried over to a LOT of D&D computer games over the year (which is why I don't trust save-or-die spells much)
