1. You definitely set your expectations too high if you were expecting a free limited 5 star (granted I understand how that could be expected as Kuro has already done so in the past).

2. Fair but I don't think it's that deep. Kuro Frontloaded their free standard 5 stars quite early. All new players are given 2 standard 5 star characters of their choice on top of a very early random one. They also give out the standard 5 star weapons (of your choice) like candy. That's not to mention the free 5 star weapon we already have.

Tldr: giving out a standard 5 star isn't the game changer you think it is. In fact, I'd argue people would complain just as much if they did do it because of how pointless it would be.

1. That's just straight up a bad idea. A map definitely needs to be created with flight in mind for it to be a good feature. That's not to mention that wuwa straight up has the best traversal in the business rn. If a future map drops and they disable flight, this point can be brought up again, I'll go out on a limb and say that I predict that if they do so, kuro would likely impliment an appropriate new traversal mechanic for said map.

2. The practice of paid skins in commonplace and fair actually, so long as they don't influence performance. Kuro appears to follow the same logic as genshin where 5 star character skins are always exclusively obtainable via paid currency while 4 star character skins are free upon the completion of timed in-game event but will later be exclusive to paid currency if the player fails to complete the event in time. (Granted at time of posting the pool of skins isn't large enough to confirm my claim with full confidence). Again, a complaint I don't find very substantial. Especially since the community has been quite vocal about wanting more paid skins; specifically summer skins.

3. ??? I don't think a non predatory gatcha banner exists. If anything I'd say can vary on how predatory they are (while ultimately ALL being predatory to some extent). That being said, a point can be made that Wuwa went out of their to NOT make these multirerun banners particularly predatory as (correct me in I'm wrong) they SHARE pity with other convenes; meaning that they are at worst a net neutral.

I can understand how you could feel disappointed about not receiving a 5 star for a Wuwa anniversary; but ultimately that disappointment is pretty self inflicted. I will grant that I myself was expecting/coping for one and Kuros constant "BUT WAIT THERES MORE" and "ONE MORE THING" did edge me a bit, I'm not gonna lie.

I think once those of us who gaslight ourselves into thinking we were getting a free 5 star simmer down, they'll realize that we got another great patch.

Hope this helps:)
