Shade when past 15/20k Corruption (reg not conf)

Hi guys, somewhere along the way after 15/20k I can’t figure when but Shade’s HP suddenly seems to stop scaling and actually seems less than at those corruptions so in essence he is easier to kill - his dmg is still insane but his HP seems bung. He seems easier to kill at 30k with far less time/dmg done to him than at 10-15 even. It might pay to check as the seasons go on and the power creep greatens more people will push higher corruption etc.

Thanks
