Doesn't really matter how many people play the job, that's more of an end user/population problem. Job popularity among the masses is largely irrelevant when making updates (they are doing them to all jobs eventually, so order don't really matter).
People didn't value RDMs too much until they made an ambuscade month where it excelled. The adjustments are unique to each individual job, the people who play the jobs will appreciate the improvement. Or maybe it will encourage more people to see what the job can do if it gets just a little attention. But, if it doesn't adjust them up or down this imaginary "list", really who cares? Plat whatever job you want and rock out with the *** out.
