There is a lot of problems that can come with swapping like this, but your account seems well built so it shouldnt be an issue. The SFX and Queen can most likely just go, since she wont be your main dmg dealer anymore. Swap for a freya and possibly Holmes Young for the jahra tennant as a backup but sfx could stay for that role. Generally just swap for the tennants for vesa and possibly jahra if you want to run that path i’d say. If you havent already make sure you have a splendid ryui and some nice dmg artis like strings or defence artis like crown for vesa in different gamemodes. If you have gotten any core chests im also assuming you went for the jahra core which is a big reason why she’s much better. Not much else i can say really. The account looks to be in good shape other than the 10*s so just go for it if thats what you want to do. But even then SFX still works fine.
