why can't you post this on every bug report? just for the players to know if you have it logged in or not. Afaik rioters read every post, right? (it's fine if you only answer to this part)
Rioters from various teams do read the boards, yes. I personally try to reply to as many skins-related issues as possible. To play devil's advocate, it can become difficult to reply to each thread, as well as tackling our daily in-house work, especially with the release of larger patches; Star Guardian or Elementalist Lux. I know I've had issues keeping up with replying in the past, which is why I've started tracking all skins-related bug fixes in the patch notes. It's a central location for any/all fixes we've done. It isn't perfect, but it's a start for better visibility.
I mean, i would really love this feature on the bug boards in which, if a rioter looked into it and logged in, the post will show green, or the title, or a sign or something (a thumbs up). If it's not a bug, it will be red (or thumbs down). If it's nothing, grey or something.
I agree that it'd be a nice feature to have. I don't manage the structure of the boards, so I can't speak to what kind of work that'd take. Happy to suggest it, though!
How about letting us search in your logged bug files to know which ones are logged in? If they're you've got 1 less report per player
That's a hard no, only because we also have bugs logged for upcoming unreleased content that's in testing - it's a huge security risk.
