Really ? i think the potions in BG III are ridicoulusly strong!
I mean potion of haste ? giant strength and invisibilty potion for example
I think I didn't formulate my thoughts well enough on that one.
I didn't mean that the potions are weak. I meant that with spells and class abilities alone, I could roll through the game easily enough. So I kept hoarding the potions, for "just in case". I didn't even try the potions you mention, in fact I probably only drank health potions. If the potions are indeed battle changers, they are very unnecessary battle changers.
