Partner, even in the main games event Pokemon are under leveled. Rotom is at lv 15, legendary trios are at a lesser level, Shaymin is at lv30. You're supposed to raise your Pokemon; it's the premise of the game. You really sound like Paul from the anime; catch them strong and if they're weak, release them. You don't want to train a low leveled Pokemon, don't use it bro. I'm not trying to be rude, but come on.
