Isn't Rat King the weakest of them all?

Am I the only one who thinks that Rat King is the weakest character here, and is just a community joke that should have never come to reality?

Like, the entire point of the character that he is just a toxic rat guy... Seems pretty blunt compared to pragmatic chess-playing planner or an onnipowerful all-seeing prophet who claims she is stronger than the Patrons themselves, no?

What exactly did we find in this guy to massively vote for him?
