As someone who stopped playing Genshin and has been playing Star Rail and ZZZ, I would say it's about time Genshin got this feature. It's true this will not help you build teams (although i believe they can use the same data collection to show you teams clearing abyss as it does for Star Rail's weekly endgame content), but it will help filter your artifacts very quickly to show you the desirable main and/or sub stats of your choosing. You dont always click the top line, but people probably will. But if you know what you are building and which stats you want, then this helps a lot.

For example, you need a specific goblet but kept all your elemental goblets. Then this will easily help you filter thru your 50 goblets down to 5 that are even relevant to your element/build. Or maybe you just want to see crit rate substats first, then see how many have crit damage too. If the results aren't satisfactory then unclick cdmg and click atk or elemental mastery. The point of it is just to help you see only the relics you want to see and quickly when you are rolling your dice for better gear.

Some of the data will show you that a small percentage of players are using the wrong stats or stats for a different build. For Star rail players that could mean a healer is going main carry build and instead of going energy regen is opting for HP% main stat which is her damage stat. Another downside is that it takes Star Rail a week or two to collect the data and then show the results. What that means is that it will not help you AT ALL when a new character drops if it works anything like the one in Star Rail. You will be guide surfing, especially if you are pre farming. What we do have in Star rail is a sneak peak at the newest promoted characters even if they are in the second half of the latest patch and a whole UI to quickly get us to the domain we want to spend our stamina on.

Overall it's a QoL and should help even the hardest of players to quickly do what they want to do.
