Heal is maxed out--it's a 5.5 sec cool-down, but it heals 95-200 HP (and Devs? Could we maybe make that not such a wide variable sometime?). It likely won't fully heal you, but it might keep you alive long enough to have a chance to suck a pot. I wish folks would bear in mind that while it has an 8m effect area, it doesn't cross voids or go around corners. I have to be within 8m of you, in the same area, so don't demand heals and then grumble about "stupid mages need to stay back". We can only stay back but so far if you want heal-spamming. And yeah, Azrael, I'd agree with you--folks are going to need heal pots whether or not a Mage is present--we can only do so much and there's a lot of stuff that one-shots us or drains mana down to bupkis.
