isn't that basically just the genshin formula? highly doubt dehya and tighnari are gonna have another banner ever again, maybe chronicled wish but that's it.
Not exactly because
1-They made it clear from the start Dehya and Tighnari were going to standard banner and ther first banner was simply the opportunity to guarantee them on release. Star Rail never added a standard 5* or implied old units would go there..
2-Star Rail is not throwing them into standard banner, they're going to "
limited banner 50/50 loss pool". This means you can't get them on standard banner, beginner banner, 300 roll invitation and probably not on anniversary freebie either (we'll see).
Every limited 5* in genshin has always been limited and marketed as such, which is why genshin model has such a strong FOMO "value". People roll on characters with the expectation that they can't be obtained any other way and it might take years for their return.
Like, some people don't give a fuck if Shenhe is not top tier, they waited over 2 years for her and they WILL guarantee her. It would suck for them if Hoyo revealed she'll never have a rerun again and the only way to obtain her is losing 50/50 on limited banner.
And i got something wrong previously about honkai 3. In Honkai 3 it's not a cash event but a crystal spending event, meaning F2P players who roll during the event can participate and you're rewarded for hoarding until the next event.
Leakers have "confirmed" the star rail one will be exclusively paid currency so f2p won't get anything from it...
