Need help with Molten Strike build

Hello,

so I did a molten strike build for this league. Here is the PoB link (https://pastebin.com/afYaNM4U). I hit 90 and all felt good until I hit red maps. Some of them feel very rippy. Any suggestions or fixes I could do this build defensive wise or in general? :) Thanks.
