Healing potions are too abundant to begin with. No one needs a cleric in their party and you don't need to throw potions. There are so many lying around every character should always be well equipped. Not to mention the rest system and revify scrolls are always there to bail you out.
You could probably also argue you don't need a spellcaster since there are so many scrolls available and anyone can cast them.
Yep to all. Exactly that's why I said you don't need to throw and catch potions. Everyone can use a Bonus to use a potion every round and keep fighting, and with group inventory, if 1 character runs out, just take it from another no matter how far away they are.
HELP feature makes it even more silly. No Medicine check to see if you revive an ally. No healing kit needed. Just HELP and 1 HP restored. Whereas if a Medicine check is needed, and you suck at Medicine, OH that healing potion is SUPER important to save a friend's life.
