Is the best passives i came up with so far, can anyone see a better path/improvements?

Help is apriciated//maybe Even awarded ;)

Bump

Bump, 10 ex in std if u can Improve the tree

Witch starting node is ineficient.
Written in blood is not the best either.
Holy fire is one of the best dmg boost for RF since it is pure burning dmg.
Those nodes in the shadow start are inefficient too.
Explosive inpact is almost like a must to have on RF.

Slightly less ES and way more dmg with this tree.
Also, optimising without knowing what kind of gear you have is hard, for example weapon could be at least 3 different unique, shield could be a rare ES shield with leo mod (in which case more life regen is important).
Do you have the shavronne ring, which regens 3 or 4% of ES in the right ring slot?

Anyway here is the tree I would use on an LL RF.

Switching to witch and fire nodes can grant you 1 extra jewel slot with same dps.
