I've noticed a weird trend of some players who main one agent having an affinity for the same other agents they play.
I get it when it comes to duelists being more comfortable with Kayo and all, but some of these don't make a lot of sense at first.
For example: take Mada and Alfajer
They both play KJ and Neon, which I've always found really interesting role-wise because they both require completely separate play-styles.
Another example is Sova and Raze, there are so many players that Main sova but also main raze on certain maps.
Just a late-night thought.
