Offline Patch download (msp file)
I hate calling this a "new idea". We have offline systems running the "FRL" versions of Acrobat Std and Illustrator. There is a patch site (though hard to find) to download the offline msp updater for acrobat. I was just instructed via support chat that an offline patch doesn't exist for illustrator, and that I have to go back into my admin console and generate a new package installer to bring on. That's a lot of extra work for something as simple as patching.

Oh, and I wouldn't even mind if the patches were only available within the admin console login as a way to force a support agreement. It just needs to be an easy clickable area with offline downloads.
