RF Late league?

Hello people, i'm doubting about the following:

I'm a Tarkov player and it seems the next week or soon**^(TM)** will wipe the game (it's like leagues for PoE).

I was about to start a new build with 70Ex (even more if i sold some items) but knowing that Tarkov will wipe i won't be playing a lot of PoE. So i guess the only choice now is to push my RF build to the max.
Do you have any tips to push even harder the damage and surv of this build?:

Using as a reference RF Pohx guide, i should get ashes (but i don't know for what reason lol), aegis (def), melding (cap res), 2 sets of clusters? (dmg) and with all of those items do a respec of the south side of the passives and focus on west and north clusters.

Any tips to push dmg farther? (maybe ashes is not that mandatory and i could use those 45Ex on other items). For reference, now i'm currently doing 65% Blight (Ravageds), 30% Expedition, 5% Betrayal. Want to switch to some bosses/Delirium (i know, RF/FT is not great for bossing).

Thanks in advance!
