I figured a $250 flat rate would be fine, as its a simple healing spell that can affect the littlest calculations.

Rank 1-6 (15 / 17 / 19 / 21 / 23 / 25). Also there is no Team Restrictions on Blood Mage. You only assume "2 per team" because all you really need is "2 per team" to sit back and look pretty. Also based off the Blood Mage's kit as a whole, he's got as many on-hit effects as a =Jack=. Also since he can mug people for a couple dollars here and there, and kill for $300, it'll be fine. The easiest counter to all of this is to rush the Blood Mage without penalty since he can't mass light people on fire anymore. At least then you won't get one-shotted after killing him (stupid Hell's Demon)
