I use less pots with my Mage than my bear or bird bc of heal. Why wouldn't you want to invest points in it and use it as much as possible? I don't get where this question is coming from. Be glad you have that skill and that it's so useful. Yes, teammates should also use pots to help, and not rely solely on the Mage. But if you want your team to succeed, healing and/or reviving are musts.
