The
did heal, mate. Not only all your other units that were inside of its circle, but also
.
It's a bit hard to see but pay attention at around 0:21 and 0:22, in the video:
-
At 0:21, you can see Braum having way less than a full " mini HP bar ", which represents 300 HP, or so. It seems that he had, at least, half of hat, which is 150 HP, or maybe even less.
-
At 0:22, when he was knocked up by
, he actually was healed. You can see it when he reaches the top of the screen and as he's falling back down, with
's bomb on his head, before it explodes. His HP went up and had some HP after the mini HP bar. Which means, he had more than 300 HP. Probably around 400~ish.
He was healed for so little because he had the Red buff on him, from Tristana attacking him. Also, he was still under attack when he was airborne off screen, and falling down, which made it difficult to notice that he was actually healed, and instead, all you saw is him staying at under 300 HP.
In patch 9.17, the healing changes kicked in:
- Grievous Wounds Healing Reduction: 100% ⇒ 80%
- Redemption Healing: 1500 ⇒ 1200
20% of 1200 is 240.
So, Braum went from having, at least, 150 HP, to 390 HP (150 + 240 = 390), in that video. Which is a rough estimate, of course, but it is in line with what we see in the video in terms of HP bar length changes (even if it's a bit tricky to notice at 1st glance). Not to mention, Redemption successfully healed all the other units as well, so I strongly believe there is no bug here.
