SE will most likely further nerf coil 1 when coil 3 comes out so stay tune. To be honest, if they want to make the fight easy as in people can clear it in one or two tries they'll need to severely nerf the mechanics, like removing all the one shoot mechanics ie: Conflags, Twister, Divebombs to the wall..etc. They should just make it a tank and spank fight with the occasional AoE to dodge.
