It was played in game, if was talked about several times, it was posted in OW several times, it was posted in Arcaea several times. It is on the wiki as a reference so people don't have to ask for it to be REPOSTED for the 11th time.
Further to that the wiki IS a IC and IG resource. You have been playing the game for long enough that it should have become apparent by now, even if you have missed the several announcements to that effect. Everything Galiard did was talked about IG to some degree, then posted to the wiki for easy access. That way when you wanted to view it and someone wasn't online that had it to post, you still had a place to go and find it.
