Ran into this problem this morning too. No characters at level 80 yet so I don't know that I even have any Aquatic Resources (certainly can't find them anywhere in any character inventory or currencies at least). So until I can play along with this convoluted gear shuffle they dreamed up, I can't get my GS tokens?
Just another example of how poorly thought out everything in 7.0 appears to have been.
I have a lot of respect for what development teams have to go through, believe me. But at some point, you need to have someone who really has the ability to see how everything will work for real in a live environment, not just in a planned, optimized, "controlled environment" way. And then make adjustments to the plan if it doesn't match up between the two after testing.
This is clearly missing on on the SWTOR team. There's just no other way to see it.
I'm just waiting for my sub to run out at this point. I play less than at any time since I came back in December 2019, to scratch the itch of wanting to play a bounty hunter again when the Mandalorian hit. I'd played off and on since launch, during breaks from other games, but I've been a steady subscriber here since that return.
