The final battle with Lysandre makes me sad. It's one of the hardest battles in the game, but right before it happens, they literally hand you an uber-powerful legendary Pokemon. They require you to catch it, and give you an option to add it to your party, even if your party is full. It trivializes the entire climax. I didn't use it and had some trouble, but they practically beg you to use it against him.

my yveltal took out his starting mienshao but other then that my team one shot everything on his team, for a final battle it was scary easy including gyarados(although zap plate raichu w/ thunderbolt had something to do with that)
