You get fourth level spells at what, 14th level? You can afford a few superior Ardor IV weapons by then. It isn't like rangers never a few extra weapons sets about them.
It's 1 step to chug a pot vs 3 steps of swapping sets, casting, and swapping back. I'd rather spend the gold for the quicker buff and having more inventory slots available.
