Sword of Spirit
Legend
This indeed. I don't think Pathfinder thought through the societal ramifications of Create Water at will, and I've had to argue down a player who wanted to keep acid splash-ing something until it was gone. But there's a huge difference between 16-18 a day and unlimited, so I'd be OK with that.
And it will be nice if D&D Next handles these sorts of issues with better guidance. For instance, as DM I'd be a bit unhappy if my player used at-will acid splash as a way to eat through any object that was in the way. On the other hand, as a player I'd be irate (at least on the inside) if my DM didn't let me do something that darn well should work!
