We must come up with what's OP and what's not. It's annoying arguing all over this wiki about that. Now, begin.
What is OP? Over powered.
Someone who can kill Sauron. OP.
Someone who can kill gods. OP.
Someone who is a werewolf. Not OP.
A minor Maia, not Op.
Having an Unkillable spirit form. OP
Someone who can shapeshift into a dragon AND do a bunch diverse magic and no weaknesses. OP (that's why I changed it)
A weredragon that's a mere side character. OP
Get it? You all know pretty much what it is. Now, we need to set a Standard so we can stop this endless criticism and OP shouting.
