I believe you can also get rear sprockets with nylon bushings in the stud holes as a sort halfway house to a cush drive, which may help

Don't know if they are retro fittable.
There is already a Cush feature in the clutch....

In theory, there should be nothing about running in 5th for any length of time that would affect the longevity of the locking lugs on the 3rd/5th pinions (the two components that engage 5th). Even if they bash back and forth on themselves some, that shouldn't do too much to change the undercut angles of the lugs, nor round over the corners, the two of which are the principal causes of the problem. Sloppy and/or very frequent shifts into 5th are another matter, though, and it might be that bikes with a lot of road time just get more of that than dirt bikes do.
It would be interesting to see the wear on a high mileage road-ridden WR that hasn't started popping out of 5th yet to see what is developing.
