2 Rounds one account then 1 round multis

I want to have the choice to choose between this two options because when i get tired of multis i want to go back to one account and vice versa.

Translation ↑: Already gave this suggestion, so that with other things, it has to be a multi and a round single, not to lose players and the game does not get sick
