PBEM campain issues

Just as an odd thought, WHY?
The purpose of a campaign is to increase the experience level of your troops.
Wouldn't a whole sale replacement defeat that purpose? I could see it if a formation was wiped out and you had no higher experience level to replace.
IT might help against the AI but vs a HI normally a company of MBT's at 50% that have increased their experience by 20 points will wipe the map with a full strength MBT company at normal experience levels. Maybe after the first few battles when the increased experience isn't as large, but after the 3rd battle, you should have a core of 'elite' units. Losing them means starting over.
