SukuiNushisaid: Would Jagex be willing to allow us to transfer loyalty status (and existing loyalty points) from one account to another?
Sadly no. They probably could, but in their eyes it'd likely be less profitable than not allowing to do so. Though, if you were able to transfer your loyalty stuff across accounts, even if only once, then people who are going to quit would RWT their loyalty stuff to those willing to buy them for long term use.
SukuiNushisaid: Technically, me having a new account doesn't undermine how ''loyal" I am to Jagex. (Gosh, I sound like a cultist straight outta Gielinor.)
Technically you're correct, but yeah, it doesn't change the outcome.
