The goal of this build was to create something that is able to invade low levels, looks like it could have been a starting class and is not overpowered.
The build is able to use almost every real-world weapon in the game (except for Ricard's, Murakumo and a few other heavy weapons).
In order to not be overpowered I recommend not upgrading the weapons beyond +5 raw (not upgrading for burg at all etc)
