A major point of contention for some Genshin Impact players is the difficulty of rerolling the game. The gacha mechanic is introduced quite late compared to other games, and there are certainly penalties in place for those who try to reroll. . First of all, you'll lose any rewards for beta testing or for signing up for the game early if you switch accounts, so it's not even worth rerolling.
Second, it appears that miYoHo is handing out bans to people trying to raise, though it's unclear if this is official policy, a rare occurrence, or just a rumour. Anyway, if you want to delete your Genshin Impact account on PlayStation 4, that's bad news.
At the moment, there doesn't seem to be a way to do this, as your Genshin Impact account is linked to the PSN account. On PC and mobile devices, you can use a miYoHo account, so rerolling is a fairly simple process of creating a new account, if you want to try doing so. On PlayStation 4, you can't do this, as it would mean giving up all your other games and purchases.
Frankly, raising doesn't really seem worth it at this point anyway. We've spent a lot of time in the game, and so far everything seems reasonably fair when it comes to difficulty, getting new characters, and everything else. If anything changes and someone finds a hassle-free way to reroll on the PS4, we'll update this guide accordingly, but for now it seems there isn't much point in it. to try.
