Let's put it this way.
Not everyone is satisfied with a certain map.
With the exception of "Trinity", which has an exceptionally long running time, most maps rotate in about two days. When it's short, even a few hours.
With the new 1-week rotation feature, now, everybody gets to see their most hated map for one whole week.
Ofcourse, in reverse logic, everybody would also see their favorite map for one week, too.
...
So, simply put,
Would the fun of your favorite map for one week, overweigh the dismay of seeing your most hated map for one week?
...
For me, seeing my most hated map for one whole week, is worse than seeing any of my favorite maps for one week.
