The 5* ticket gacha said its Maple only. I didn't know they plan to add more to the pool and thats why I said its unfair that devs pinged people on discord but didn't bother to do any scroll bar text announcement or something like that. So I had just info that Maple is only in gacha, and as someone who had have zero rainbows till then, I rather pull her than risk them changing something to for example even lower 6* chance from 5+ ticket, or something. I play maybe for around 3 months total, but I didn't really pay that much attention to all the mechanics/behind scenes stuff, so I don't really know what to expect them devs to do.
Well, not like it maters as I already used the ticket, so can only be angry at myself that I used it the moment I got it.
