Which Ascendancy for PP in 3.3?

I want to build a PP character to try and spend the rest of this league with, hopefully kill some Guardians and maybe Elder (never have before). Which Ascendancy/skills would be the best for overall mapping & bossing potential for this league?

I find my Bestiary char TitanAwakening rather nice for comfortable game and plenty of upgrade for jewels and abbys league items. Got that chest tho, very nice for lab with pantheon that give immune to poison, now tho its possible to get it on ring but hardly the same. Got easy time on him for what ever i done.

Bit hard to squeeze that ring it got and find watcher eye, that extra mana + life on hit make it so match better.
Else i think something like Slayer or Scion with bow is probably a good option.
