PoE Responsible-Pay-2389 builds

I was working on a molten strike chieftain starter and ended up coming up with this: &x200B; The defenses look pretty nice, and I was planning to replace 2 of the skill gems with returning projectiles and trauma support when they get added. I wasn't really sure how to get the correct dps in pob for molten strike so I'm just hoping it's significantly higher than what the number I got is lol. &x200B; Any suggestions to improve this? Going non crit for league start cause it just seemed easier.
