One Hit Kill from Hadi of the Flaming River

I'm repeatedly getting OHK by Hadi of the Flaming River doing that wide flame wave attack.

75% Fire Res, 20% armor, 53% evasion, 1500 Life & 100 ES.

I have no negative afflictions against my survivability, nor increasing their damage .. and yet I have repeatedly lost all health in one shot (& somehow only lost less than 300 honor lol).

I would understand if I had taken some prior damage before the hit, or if I got double whammied from Rafiq of the Frozen Spring but OHK from one attack is just ridiculously unbalanced & it has to go. Nerf it, nuke it, do something please.

Please give me a choice to not have to go back into the same high-ES meta from the launch season .
