Is because what are you saying i want a break on legendary raids or masterball in raids (the best way to make a consensus between me and you, but they have to have a rarer drop in pokestops (like the evo items, 7 day streak item???) and raids, you reach to a raid throw a masterball, whenever the iv is and thats it, people who want 100 ivs would continue to make raids until reach them, spending their money on raid passes) or a completely new way to catch them (soloable or not, but unlimited time), a game is proposed to forget our diary prroblems and stresses, but not to stress about a limited time thing like the legendaries and make raids (attention, im a suburban city player).
About the second point, I only have 17 years, I can take the driving license here in Portugal when i get 18 years (not 16 like in the US) so Niantic should think that the most of their playerbase have my age and are childhood, so they would never be hardcore raider without a car.
Finally, after the Rayquaza announcement in normal raids, Im very critic about the EX raids (i have 2 mewtwos, attention), I think that mewtwo and ray are in the same boat, so if ray was launced in normal tier 5 raids, why mewtwo was not the same and EX raids to mythics???
I hpoe that this quests found in the code go live and we can catch legendaries and mythics and/or masterballs
