"Research legendary rewards isn’t as cool beans as I thought"

#PokemonGO: I for one was excited to hear that 6 legendary Pokémon would be available for the 7 day researches. Considering there are so many legendary Pokémon I missed. EXCEPT! The only problem is I’ve gotten Zapdos EVERY. SINGLE. TIME! 4 weeks of research? 4 of the same legendary. It’s so irritating. I know they will be available next month as well but I really think there needs to be some sort of balance for this. I’d like some other legendary Pokémon and I feel like after putting in 7 days of research I should be rewarded with something that I don’t own. Idk maybe it’s just me but I think this is an issue via /r/pokemongo http://bit.ly/2EUrB2n
