you CAN doesnt mean "best to climb".
I think this works pretty well, I must be doing something wrong because my champion has a high winrate when other people play him
they mean that if a player is skilled enough they can play anything and climb
if you aren't skilled enough (you're not), you're better off focusing on a handful of meta champs for your role and mastering them
I got called a troll for picking tank jayce. what is meta if not tanks?
