Game wont Patch , from 2.1

I synced over bit torrent sync and game wont load.

10 hours to re-download , bah....

Smaller files ? , Delta-Fast patches.

3-4 gigs of EQ2 can be downloaded in far less time , SOE patcher works fast.
if the file is too old to delta-patch , it will just get the newest copy, and delta-patch everything it can.

but incremental downloads on a fresh install insane.

DL if file to to damned old , ie the dat files the download newer ie 2014 and a few delta's

secondly if a file or 2 is quite damaged , their isn't a fast repair means.
ie if only 1-2 files are corrupted , then it only takes 50 more hours to re-download.
and your backup cant be trusted.
