Did the tier 1-7 gear get unique currency per tier on test server? My understanding is that vault gear will stop when that is implemented.
i dont think so, i usually dont play old content on test since i dont even play that on live but i will take a look when i am on test
Vault gear never dropped on test, it was something that accidently got added to a live game update even though it wasn't ready yet. So they probably didn't patch it in to newer builds of the test server.
Since it is easier, this link will also work for discord: https://discord.gg/dcuo Vault gear will increase over time. I am following up on exactly when.
Generally, the vault gear item level cap will increase with each episode. It launched already set to the appropriate level for Episode 29, though, so the next time it will increase is with 30.
