So, I was super excited about a'lil bit more blood utility in raids, as the current worms are garbage.
And I didn't see much talk about it elsewhere.
When I first read about the change I napkin'd it to be about 6 times the healing, then I decided to test it out.
With abit of setup, I managed to push out roughly a 1.3 million heal from a single worm...
126k hp worms, 12 stacks>360% of health to healing, crit doubles it and then a 40% modifier from glyphed VB.
1,271,229 in total. Leaving VB and the crit out, it's still a solid 400k+++ heal
