I didn't have too much trouble with Diantha, but when I pulled out my Charizard and mega-evolved for a flashy finish and she mega evolved her Gardevoir in the same turn, I was hype as fuck.
That was about it, but there wasn't much else.
Cut to AZ walking up during the parade, and initiating a battle. I was hype as fuck.
I was thinking he was gonna be secret-final-boss difficulty, or at least more difficult than Diantha.
And then when I find out he only has 3 somewhat underlevled mons, I was pretty disappointed.
Mind you, I understand that him not relating to his own pokemon because he's so depressed (and thus them being weak) makes sense in the story, but I was really hoping for a tougher fight. In that sense, I hope they amp up his team in Z.
