After a few tests, I would say that the 5% healing bonus can be completely removed as it is now completely trash.
I would really understand some changes, but now we are in the pretty same direction as before. Why not give 5% barrier instead of healing while being in life force? You can limit the maximum of the barrier to ~3k and start the timer to lose the barrier when you leave Reaper's Shroud. Just an idea, but that could be a good compromise.
Reaper was nowhere meta and doesn't deserve to get worse. As I said before, I understand that changes have been made here. But I think these changes are too strict.
