The "You're sending messages too quickly! Please wait X seconds before trying again" message has been appearing far too often and eating messages which were sometimes full 2-3 seconds apart. This has made no-mic raids much more annoying, and forced rewriting messages multiple times when trying to hold a conversation over in-game text chat. I haven't seen anything related to this from @BungieHelp, but it's been extremely frustrating as a player who mainly doesn't use a mic to Raid or chat with mates
