"Could not possibly get any better"

[Tobius]

Trying to get my Frogloks of Guk faction to "Could not possibly get any better" levels.

Don't ask why, I know it's not in any way useful. I don't care.

Feel like I have killed enough for this to happen.

Does anyone know if that message doesn't appear from old world mobs or if frogloks are broken specifically or something like that?

Anyone themselves have max faction and can confirm it does exist?

Thanks,

- Tob
