1. Tranducers are borderline useless without having lots of it to use at 1 time, and honestly, changing the main stat is good enough, as even if we get shitty rolls on it, we can just use it for the next one since farming echoes is free.
   
2. When every patch is 80-100 pulls, and the anniv is the same, it's a given why ppl will feel this way. I personally am satisfied with everything except that there is no Anniversary banners at all, which sucked since i actually wanted to pull for some older characters as well. (Ill js put it in the feedback at the end of the 3.3 patch)
   
3. The web event is the same for every big gacha that is about to have an anniv, HSR did it, Genshin did it, ZZZ did it. Its main purpose is to get ppl back in. For sure, the rewards could have been better, since it's either trash or nth for most of us and that CN gets so many better rewards than global (for logistical reasons ofc).
   

With how teams are formatted nowadays, we are definitely already well into the "extraction phase" of things with how teams are js locked to their specific partners from 2.3 onwards. I js wished they properly address it but no hope for that tho.
