After replaying this, I'm gonna be honest: they really should have let you catch Rayquaza when he appears in Sootopolis.

Sure it would make the game a little easier, but I feel it would make for less awkward pacing. As for the postgame, you still would have a ton of legendaries to catch, so I don't see the problem.

Good game otherwise, though. Haven't decided whether or not I want to do the Battle Frontier and catch the other legendaries yet.
