I do not agree with this proposal due to several options.
1- As you all know, it is not easy to be on the ladder, if a person has the possibility of being on both servers, why not?
2- I believe that this does not promote frustration but rather the motivation to try to get on the ladder.
3- to finalize my opinion and my contribution to this issue, I believe that the trick is to surpass oneself and not make the system easier, otherwise it would be boring and would not have the merit it deserves to be on the ladder.
