What Hikari doesn't get is that a strong argument doesn't correlate with how the meta feels when something is broken. A guy could say "yes xurkitree was broken because it was strong." and you would call him an idiot even though he is correct and then disenfranchise him. At the end of the day, it's not opinions that get things banned, it's how people feel when they play against it. People who get reqs go through 70 games against mega latias and can obviously tell its broken, they just can't put it into words.
