2h sword berserker in need of advice

So yeah, I'm playing a Berserker inspired on Guts, from Berserk. I had Uber Izaro down in seconds, but mapping in 13+ have been hard. I feel elemental damage bosses don't let me heal fast enough. Should I go for Phase Acrobatics?

I'll take any advice.

Ps: I'm saving exalted for a Starforge, that's why I picked Blood Magic.

Vaal Pact is only three points away, and would give you twice the leech.
