Sad part is that the rewards for battle will be crap and you do not really earn anything. I wish more games had a difficulty systems like it though, so people who never played before can pick easy and others can play brutal.
Yep, one boss fight takes place in a small room where you energy slowly drains the whole time and the boss can do an extreme amount of damage, move at high speeds, and turn into liquid to avoid damage. You can also run out of the ammo you need to beat it faster.
True, but that is just mirror mode basically with harder enemies.
I do use other Pokemon for Fly, and all that stuff, but only battle with my starter. I am just going to continue waiting for Alpha Sapphire and Soul Eater Volume 23 later this month. They come out in the same week!
