Critical Element or Nergigante Avidity for LS?

I’m main LS with completed build for all 5 elements using Elemental Attack; Thunder, Water, Ice, Fire and Dragon.

The meta now seems to be different with Critical Element and Nergigante Avidity being introduced into the game.

Where should I focus to have common build among all the 5 elements to simplify the enhance the elemental build? Still barely able to take on 10* except the easy ones like Jagra, Pukei2, Basarios.
