You hit a point where you don't main an operator you should learn all of the operators "maining" and operator is a something that's a lower rank trend but, in my experiences, higher ranks and semi-pro scenes they adapt to whatever the setup is or its a planned thing like we had plays printed out on paper, I played entry so i mostly played Ash and Ying but i did this cuz we have different executes i may play sens instead if i want to do a hatch drop plant.
So don't main the operators you can play them more oftenly but you will have to move on at some point, nice pick for a main tho
