I'd planned to post briefly this morning to share that I was so very lucky as to catch a 100% IV Zapdos yesterday! Yay! And then I was going to say that I actually hope summer legendary season will end tonight; I'm game-exhausted by these limited-time-only availabilities of the legendary birds. And then I was going to comment on the rampant Ho-Oh speculation. But...
Apparently, Mewtwo has been a raid boss at Pikachu Outbreak! People have caught Mewtwo! And clearly there's this Articuno right now, here, when we all thought that Articuno wouldn't be seen again in the game for many months, if not a year, if not ever.
Why does Niantic do these things on Mondays (work days) instead of weekends?
If all the legendaries are back in the game at high availabilities, I may perhaps feel a little ill-used or tricked for having invested time and effort in catching them while we were told they were limited-time-only. Hmmmm.
Addendum 10:56 PM: Niantic has spoken: Mewtwo and "other powerful pokémon" are coming soon to "Exclusive Raids," and all 4 legendary birds are back through the end of August. Read all about it.
