Our alliance is facing a mephisto as war boss. Kabam said in the past that in war, regen would be based off base health and not modified health like 500% health nodes. This mephisto base health was around 16156 and he had 6 charges. His modified health in the boss node was 169000. When he reached 30%, he regen should be 10% of 16156, x6 per charge which is 1616 x 6 = 9696. Instead, he regenerated 16900 6 times for a total of 100k health.
Here's a video showing the regen.

We wasted a ton of items getting him down to 30% health assuming the regen would be minimal. This is ridiculous. All those items went to waste
