Ok. Let’s be honest right now.
Ex Raids are going to stay like this, and we have no influence on how they work.
Most likely there will be no other option to get Mewtwo, well, until we will get real trading one day…
Niantic is Niantic, they will try to “fix” EX Raids, but let’s be honest. They try to force us to use it how they imaginated to be. But reality is different. Look at raids. In all of raids trailer, everybody was running for any raid they saw, but here we have reality. Even in Poland’s capital city, Warsaw, there’s barely any people for raids. Similar story with EX Raids. Niantic will think everybody will do hundreds of raids with like 10 friends, and all of sudden they will all get invitation, but again, reality. Let’s imagine that there’re actually somehow raidgroup that with 10 players makes hundreds of raids daily, but they continously miss invitations. And all of sudden, level 7 that did one 1-star raid got his first invite. Im not saying that that level 7 player didn’t deserved for that invite, it’s just absolute random mess. So simply, when Niantic creates something, it will most likely stay forever, even if it’s very hated.
