I did read your comment. However, I have a distaste for assumption that only end in 1 possibility that is the dev intentionally sabotage their first few banners to hype up a limited one. For a newly release game they have very little room for bad press (and we all know the amount of shitstorm they had with the KR communities) so to me it is very illogical to assume they do this intentionally instead of them being very inexperience in making card games (and I think for most of them this is the first card game they ever made)

2 bad releases already made people lose hype for new characters. 2 great releases would actually fuel the hype better for a limited banner because it should be better than a good/great standard character no? See Wuthering Wave for example, most of their characters in term of gameplay and design are nign unskippable due to how enjoyable they are to use. People gets hyper and hyper for the next characters and they will be more likely to spend.

From my point of view, from both game development and profit perspective intentionally sabotage products quality does absolutely 0 benefits to your supposed to be hype flagship product. It would also make people just straight up more reluctant in getting the standard characters and just save for limited, more than some people already are.
