Marjana and Onatel talent grid

Hello, I need a talent grid for Marjana, who is in my defense on the right corner, and a talent grid for Onatel, who is my tank. I will be grateful for screny and explaining why such talents.

Im curious about marjana myself. I have a bunch of emblems for her but just dont know which way to go. I hate that she is killed of so quickly so started down defense path thinking if she dies fast she can’t fire,but now I’m thinking maybe I should go attack? She seems weak… she is my only red sniper, and besides her myI only 5* elena and puss in boots leveled up.
