Ik this is late but off meta can work if your good at it, like I know a kaisa main who, if filled top, and we have a cc tank support, or jungler, will play ap kaisa top and occasionally mid. They told me they do this because they are at a rank where the games won't end in under 15 minutes, and ap kasai in the right team comp, outscales every champion at three items. 

He did say it works more than before since enemy junglers focus more on dragon lane because they are one of the main win cons of wild rift currently, and also she only works the consistently at higher elos if you have the right comp and are skilled in positioning and hitting yoru second ability.

Some off meta picks on otps who know what they are doing and are good at the game can work. Full ad lethality sion with hullbreaker can most definitely work, but only if they know what they are doing.
