Personally every toon I have gets 100 pots of every potion I feel is needed from level 1 and up. And since my mains are all support bards they carry wands and scrolls of the main remove/fixmepls spells even if i have them memed just because I usually cast first gripe later since I know sometimes in the middle of a quest/raid sometimes people's attention may not be on themselves.
In short I feel people should be ready to get themselves but if I notice I will usually have a means of casting it even on my gimpy meelee only toons.
