You missed that I said Luna's heal using Life Link, not IO - huge difference. I didn't mention Furia.
I didn't bring it up before cause your numbers overall are too high anyway but I agree with what TTRaw said. If you buff the totems so much then the self heal would be way too high. Of course that could be modified so he gets some portion of it instead.
If I'm a front, I'll try to stay in the field but really that's my issue. I can't see the friggin ring through the chaos. Making the ring more obvious would help. Grover's ring is OK other than it persists after he gets killed (stupid).
I think you're missing my point, the totems are a source of extra healing not a primary source. The totems are similar to Ying Illusions in that aspect. If you were to make these same suggestions for Ying then imagine how massively OP that would be. The Resonance and FL players would love it
I think you need to go back to the drawing board.
BTW, Seris got an indirect nerf to Blood Pact when combined with Mortal Reach. Losing the extra time it had cuts that self heal in half.
