Now that C9 has likely solidified their roster, here's some ideas for what we can expect from them on each map. With there being some overlap between Zellsis and leaf, as well as the question of whether or not yay will start playing Jett more if the meta starts to shift a little back towards Jett + Killjoy/Cypher, this is completely speculatory and could be completely wrong.
I've heard that leaf is actually an extremely flexible player and might be somewhat transitioning to controller/sentinel on some maps, so that will reflect here,
