Thanks for the input! I am thinking somewhere between Articuno and Lugia. Those are the 2 most difficult for my group anyway. We have done Raikou, Moltres, Zapdos all with 5 to 7. (depending on who is there) but 8 for Articuno and 10 to 12 for Lugia. Focus Blast will be more difficult. I saw one raid with Psychic and Ttar could take 3 to 4 depending on CP.
