[2.2] Thoughts about this RF inci ascendancy build

Scion rf inci build: deadeye+berserker(started as a marauder)
tree(lvl92):https://www.pathofexile.com/passive-skill-tree/AAAAAwAA2E2UoNpiaHQYVvnoQYe3Pv4KiFqDzNi9XsCgQjwtg1_Grq4-DF8LYcT2Z5scp69sr6cn7eRRU6Vo8hzOBg4ZLlBH8B8rUNR82WHvDqIADc0J9q2NFCAEs-Fz_lTPfl8_wGbtIJo79kjBBIKbtobtPMRYeWjsOJZ01aY9_KluhXs62OQiWGPAGnfjZlQnLxpsxthvOwHckFU26Z2uhNkaOCSqpwgDdUd-WfMWb9gk6-6RK702cg_jalZIHNya4Fh3ZU1xhY8aRZ1fBL6neuZTUnXLY_3qYkbXzZiNfkMx2sF07S5TBS3Tb3wOp1VboIuqe26XIcF8hwdgs3fi7_0QYgDB

some high crit spell for Elemental Overload

everything else similar for regular rf inci: pheonix, elreon jew., cast speed+spd+add fire dmg weapon->doon cuebiyari not really good(, some talisman(2%life reg)can be useful if we use iron will(6l) or can sustain empower/something else.

is it viable?
