Yes, using Tribble takes up more disk space than just having the basic game. I don't subscribe to Tribble simply because I don't have time to maintain two characters on holideck, let alone a totally separate server instance. Regardless, even if you are active on Tribble, you are still downloading the patches, even if it is piecemeal .
I am fine with the downloads, as it is part of using an Active MMO, but downloading near 1GB (sometimes) still takes a reasonable amount of time, at times. And if the patch is fresh, the download seems to take longer due to the traffic (amount of users) downloading it.
I'm not sure why the patch is that big considering it only effects the 2 uniforms, missions and ability changes according to the patch notes.
The Prometheus mesh has also been altered. Prior to this patch, the housing for the nacelle on top of the saucer section was floating slightly above where it should actually be sat. After todays patch it has decended into the top of the saucer section where it should actually be.
Considering the size of mesh files outside of any games file structure, that probably contributed quite nicely to the patch size. Keeping in mind that this fix wasn't listed, it's likely a number of other aesthetic fixes were not listed in the release notes as well.
As I said before, I surmise that the large patch size is attributed to additional data not stated in the patch notes, if that were the case I would make a suggestion to Cryptic to simply state in the general issues of the patch notes:
• Implemented data for upcoming content/episodes.
At least it would clarify where the large data sizes are coming from.
