To be fair, I almost did that myself, tried to take it on solo. That went abysmally, but apparently some facebook group (independent of me) had heard about the spot I was in, and everyone appeared and assembled out of nowhere, and we suddenly had like 11 people fighting the Articuno. We needed two tries even then.

On that note: Apparently yesterday was the last day to get it. The new legendary of the week is Moltres. I feel doubly salty about not getting the Articuno now, but I got something out of it all the same...

I wonder when Mewtwo will start showing up in raids. Probably another go-fest will determine that.
