I see your point regarding this issue - Frog takes the user information from your MIS, but does not create the network paths automatically - this is something that you can do with a CSV import/export. I think what you are suggesting is to be able to select all users from an MIS year and say "Use this path '//server/share/%username%/My Documents' as their home drives, rather than the added step of the export import.
How many additional users join in a year? Network admin's must be told at some point otherwise they would never have network accounts created for them!
In my opinion it is a very simple process. The Frog Extractor is installed on your MIS server, it pulls the data out on a nightly schedule - imports that into Frog which create the user-names based on a very customisable set of rules. The users are automatically linked to their AD accounts and can then login without any intervention from you. You can then add their home drives at any time, either with a CSV for bulk or one at a time for a couple for example.
I think that any system, such as a network or VLE is going to require some amount of administration, this is unavoidable. The people at Frog do their best to minimise this whilst catering for all system types. Don't forget that it is a constantly evolving product and things are always improving
Lastly:
I tend to find that people are very quick to condemn, and slow to thank - people are more likely to want to post a rant rather than something positive, so I hope that such cases would be a tiny minority.
Phew, sorry about the long post!
