I mean its so bogus. Historically when Japan was actually divided, "loyalists" jumped from NJPW and AJPW all the time.
I do think loyalty should be in the game, but it should be like a random attribute the same as the Homebody trait where wrestler will move.
The concept of loyalty for modern day Japanese wrestlers is silly.. was Ibushi loyal to DDT that had him for the first like 8 years of his career and built his brand? No of course not, he wanted to go to the biggest show where he gets paid the most much like most professionals. The only reason most Japanese wrestlers are "loyal" to NJPW is because its the biggest show that pays them the most money, and even then the few times where that isnt the case (Nakamura, KENTA) you see how loyal they are.
Theres no such thing as loyalty in wrestling, its a business, if you go back into RWC mods you will see Cody Rhodes with loyalty to AEW. You see how silly these things are when reality hits.
