I like the new engineering system, I really do. But, if you read through the focused feedback forum, there is one point that comes up fairly often: The ways to gather mats! Nobody is interested to sit in super cruise for an hour and wait for a USS to pop up...because it's tedious and boring.
So...are there going to be any changes to that? If collecting all the needed stuff is interesting, engaging, funny, challenging,... the exact way, how the engineering system works would be secondary.
Just my humble opinion.
For those that grind out materials for upgrade there will be little to no extra grind. Just grind out your G5 materials as usual and you will get most of the other materials as you grind out your G5 mats. For the few that are tough to get, a simple trip to the materials broker will fix that.
As to how we get materials in USS's, I am hoping that will be changing in the Q4 update with the new scanning, mining and exploration update. But the good thng with the current way and the 100 limit per material is that you don't need to throw the ones you find away anymore, and if you find some rare ones that you don't need, you can potentially break them down and use them to create other rares. I will need to rewatch that bit as I was giving my son a bath.
