NoSkill required, just FocusFire

Callouts don't work unless your team is competent.
Marking, same.

If I get someone 10%, I have to pray, sacrifice a goat, and chant a thousand hymns in the hopes people will focus on fire.

Focus fire wins 99% of the games I streak to promotions with, period.

If rank doesn't matter then this can't be a Skill>Luck mode.

Rank is not always an indicator of skill, sometimes but not always.
