[Help Needed] Need some help for boosting dps with MSChamp

Hello folks, im currently playing a molten strike champ with shield and one-handed and its doing pretty well for the last two months. I can consistently do t15 maps, did yellow elder 3 times, chimera and all best bosses excpet farul. But i kind stuck a brickwall. Im kinda lost on what i should upgrade form here on.

tell me if anything went wrong with it as is my first time sharing with it.

You are missing the two most important nodes on the tree, namely Point Blank and Elemental Overload. Just by grabbing those two your DPS almost doubles. I am pretty sure your investment into block is not worth it since you don't go all in (only 40%), so I would just get rid of those in favour of more DPS.

Edit: Another thing I noticed is that you don't take Iron Grip or Avatar of Fire. I would definitely grab Iron Grip, AoF is something you can test if you would like (enables stuff like fire pen to be more effective). Pro tip: There is a toggle in PoB called "Show node power" which lights stuff up in red if they are good.

Thanks for the replay, i made the changes on the tree you sugested (with the exception of avatar for the time) and looks good thus far. Now about the gear, what should a go for? Espescially in place of that catalyst, im in a large bid there. I have absolutely no idea what to change that for.
