Sorry, allow me to be more clear.Sorry, you're right, bias creeped in.
You're not supposed to like Elminster in this version. This version just allows you to hate his Author Insert-ness in-character.
That won't help Elminster be more hated than the constant stream of trying to reclaim Aquaman by making him overly badass making Aquaman more liked.
It's yielding ground to the argument that Elminster was supposed to be likeable in the first place.
