What is an off-meta pick that you think could work if Challenger/pro level players explored it?
Asking because I think League's biggest problem is that competitive play is dominated by a small handful of champions with nobody willing to explore alternative picks.
Bruiser assassins. Especially ones with AP kits. Demonic into bruiser kits for tanky teams. Annoying, high damage kits that can escape easily and also are extremely hard to kill.
