I'm a noob main and this is my opinion, I do have an explanation for every tier and why I put some characters in that tier
Noob at S- because I main him, and sometimes comes in clutch when your low and another player just decides to shield you as noob
Shed at A- yea, sheds miss sometimes but REALLY locks in when it comes to new players and farms them for free xp
Guest at A- pretty good players, or just a new player pretending to be in one of those edits where guests just save an Elliot healing and expecting a thanks or applause
Too lazy to add more explanations
