I think banners announcing every little thing you win/build/craft/earn is a bit of privacy issue anyway. And too much is announced... some may give others hope, that things are achieved, but most of the time i hear grumbles of frustration.. like "how many cards are drawn while you spin away 20m credits with nothing" and same in runes... only private things on this game are talents. If what is put in banners were cut by 50%.. or more, it might not be such an issue. Or put it in world chat only, which you can already switch off. That way its not splashed across the screen interfering with other game functions.
