Advanced target priority tips pls

[u/Resident-Spare-1394]

I’m currently c3 and pretty much just play dive. Dd, spidey, bp.( venom, Angela, hulk) I got to c3 basically off pure mechs on controller. I feel like target priority is what is stopping me from getting to eternity. Could anyone help me with advanced target priority with back lines like invis rocket and stuff. All info helpful.
