PoE Duelist, Marauder, Templar, League Starter builds

So I was thinking of league starting as Righteous Fire. The new masteries makes leveling a breeze, but how realistic do you think it is to migrate to this after a week or two? Are these clusters really expensive? I'm a HC player who just farms red maps...so this seems pretty cool to me to be able to play that Auto Bomb style while remaining semi tanky. Thoughts?

Since there is probably like no one playing this i just to want to leave this here in case anyone is interested in an off meta build: This is no overly optimized Build but just my own Character I played in the Archnemesis League. In that league i completed 36 Challenges with it. After that i took a break for the last league. It currently makes use of petrified blood for the overleech and for life regeneration to have a bigger impact as well as to increase the damage through pain attunement on Skin of the Lords to save the passive

In 3.14 that was my favorite build, unfortunately, that build lost more than 1M dps in 3.15 due to various nerfs But this time, with the buff of the Skin of the Loyal armor (from +1 to +2 gem lvl) and the new mastery system, i managed to get back to its original 3.14 strength! PoB: It can go up to 4M with a watcher eye! but that gets way too expensive! EDIT: 3.8M with Hrimsorrow unique glove! league starter friendly! (except for astral projector ring!) EDIT 2: I edited the tree, went more on the shadow region for crits
