I honestly believe the GMS Luminous was too overpowered, for mobbing anyways. The top 3 level 250s were Luminous because Reflection is overpowered and there's no incentive to use dark mode. It was about time they did something to fix that.
thats a lie i havent found yet any proof of korea saying "thanks to gms feedback they implemented something"or anywhere else
Because they aren't going to go out of their way to thank another region for their suggestions, that's just.. weird. They're just going to do it. Some of the things in game right now could have very well been a suggestion by GMS implemented by KMS, they just won't tell you that because there's no point in doing so.
It's like thanking your hand for tying your shoe, who does that?
