I was originally aiming for a Svarog to complete my Fire team but can't say I'm complaining since I like both Gaia and Titania from what I read on wiki.
But it is very eerily weird that I can't help but feel that the drop rate increased might be affecting the SSR guaranteed.
Sadly the "Odds" button is completely removed while using these gachas so you can't really see if any of them had a boosted pull rate.
If this is true, ideally it would be wise to save your SSR ticket until the element of your choice has a boosted pull rate.
Eg: If you want a Water team, wait until there is a Fire event and they boost Water Kamihime pull rates.
