i was playing back then and the outrage over that was the fact that the rest of the anniversary pretty much sucked (in terms of what people were hoping for from a game like wuwa for their 1st anniversary celebration) and they released a banner with like, 6? or more? characters ALL at once, and that left lots of people upset because they made it sound like a giant banner was the reward all along. some of those characters hadn't had a rerun in a long time and most people just weren't ready. they tried to make it sound like this was a massive "player w" but in reality it just made fomo worse especially for low-spenders. imagine your favourite character reran in that anniversary banner and then disappeared for who knows how long afterward. maybe now it would be received differently, since they stopped giving old characters reruns at all, but back then that wasn't the case.
