That’s the catch, though. You did not earn it if you got Tier 1 before the patch. It was not listed as a reward you would earn. You had no expectation of getting it. You did get exactly what you were told you were going to get.
Again, you literally didn’t. You’re asking for something that you didn’t earn (because it didn’t exist) to be retroactively gifted to you. I get that you could have earned The Thing if you had waited and played on a different day, and that’s a silly problem to have, sure. None of that invalidates what I’m trying to say here.
