And the issue here is that people are immediately assuming everything that was not discredited is legitimate.I can do better then that: the Pokémon X/Y leaks. There was a lot of wrong information mixed with legitimate.
It's clear his leak for Shulk, Chorus Men, and Chrom was either based on incomplete info, outdated info, or was just plain fabricated (leakers often do that if they build up a reputation). Either way, you can't assume it's made in good knowledge unless you're willing to do some serious mental gymnastics to ignore Robin.
