Sorry about the mix up yesterday. There are a ton of Guilds trying to get us in, and if we're having trouble getting into one, we move on so we can keep giving out the Mythics. It gets really hectic and we try to keep track of everyone as best we can, but sometimes we run out of time or we forget to return to a Guild we tried earlier. It's definitely not done intentionally, and I hope you understand that all of it's done in good fun.
As for the level of the account we use for those streams, it's not level 50 because it's not one of our personal accounts, so the play time on it has been limited to what we've done for streams. Unfortunately, we do not have a way to grant an account a specific level (nor can we do that for the Units we have), so it just takes time.
Again, apologies for missing Adrenaline Rush this time around. I'll ask @Jennie to make sure you guys are on top of the list for next week so you can get first dibs on the Mythics.
