There's obviously some new sets and weapons been introduced for the new reputation systems that you unlock as you progress. But whereas before we could go to DS9 and see the stats for all the different weapons and sets, this doesn't seem to be available in any form now?
So how do we find out if a set or weapon is worth building without having to build it? How do we find the new sets and weapons stats out?
The requisition projects (where you actually buy something i.e. the Borg Console) have a tiny icon in the project panel that shows you the stats for whichever item it is - you can see this before you commit to a project.
For store unlocks, there's no way to know what's in there until you've unlocked it - and whilst store unlocks don't cost Dilithium, they do require a small amount of Marks/Expertise/Commodities.
