Hunter Healer solo - Durendil vs Sun King's Salvation (Kael'thas)

All right, I wasn't expecting that I could beat the enrage. But I did. With lots of bandages. I wouldn't call the boss hard, but the whole concept of a healing fight being solo'd by a hunter is quite funny given how bad we are at healing others (most of our healing comes from leech).

This was made possible thanks to the Essence fonts dropped by the occultists. When they dropped, I used the rebooting bit band from mechagon, bandages and spirit mend (pet's heal) to get them to full health, they heal the boss for a lot of health.

Then I used spirit mend on the boss when I could. Same with bandages and the pedestals.

Finally, when you kill infusers, they leave orbs - whenever there were 3, I grabbed the +600% healing and used turtle + bandage.

I tried to reset as many vanquishers and other stoneborn as I could. They stop spawning if there are enough already spawned.
Also, when there was an infuser + occultist spawn I had to focus the infusers, to make sure they don't damage the boss.

The enrage is at around 14:15 when a massive add wave spawns, including many infusers that will kill the boss quickly. Even if the shade is already up.
From what I've seen, what matters is getting the first phase 1 over as fast as possible - aim for 5:45 at most. Heroism would have been best in the first phase 2 I suppose - but thankfully I had enough leeway not to necessitate a perfect try.
