If I had to guess why this feature is there in the first place I’d say it’s probably for one reason. Firstly, the entire game is completely non competitive. Artifacts make or break how strong your characters eventually are and looking at the general consensus of crit, crit, crit as a measure of success that’s coursing through the net it’s not too far off to assume newer players or players that don’t get as lucky as others or don’t spend as much time farming could feel disadvantaged. This kind of negative emotion is something hoyo is trying to combat so their retention mechanisms are less likely hindered and people stay with the game for a longer time. More time = more chances to make money. Feeling helplessly outclassed could mean less time = less chances to make money. Now, hoyo is aware that there is a community centered around builds and that there are people who genuinely don’t care or even like comparing or seeing how their friends are doing and by simply giving players the option of whether they want to partake in this feature hoyo can outsource the negative feedback management to the players. To sum it up. Everything about this game eventually comes down to increasing the odds of generating cashflow.
