You know, I give a damn about the frontier, but you guys is as if you ahdn't learned from your pst mistakes.

The leakers of XY gave is shit about the megastones then Serebii came and in like 24hs unlocked everything because he actually knew what he was doing.

If the npcs says the frontier is being built, then you probably have to do something to unlock it. Reviewers don't go all out, they play casully and fast for the review. Now they're saying Wallace takes over the league after the episode, and if it's true it's obvious there's more stuff left to do.
