I've also found rotating sets helps prevent set fatigue (which can lead to premature set selling).You are thinking from a usage standpoint, as a collector + user we like to rotate and experience as many different set as possible
If I have to compare, it like going to holiday at various places multi times a year.
You don’t need to do it but u generally enjoy it (especially those higher expensive country similar to higher quality chips) and also they are luxurious expensive expense as well just like poker chips
Nothing better than getting a set back in play that you had previously grown tired of and falling in love again.
