/hearthstone/.ngdp/objects/data is huge!

The directory /hearthstone/.ngdp/objects/data occupies about 54 GB. Are all the files in it really necessary? Can you reduce its size?

From the FAQ:

To download the game files, we use keg. It downloads all files in the hearthstone/.ngdp directory from which it creates the Hearthstone installation. When updating, it downloads all changed files and reuses old files to bring the game to the latest state. Since old files are never removed, it can consume a lot of space. However, if we would clean up the directory entirely, we would have to re-download the full game with every update.

So there is no clean-up of old files that are no longer needed. You can remove the whole ngdp folder and then would have to redownload everything when updating the next time.
