Let's say I hatch a pokemon, put exp. share on it, and run to the Elite Four.
In 5 battles, it levels up to 33, evolving 2 times.
Can this have a negative impact on anything, particularly stats?
i read somwhere that it is a bad thing to do though it is helpful. the best way to train up a weak poke is to battle wild pokemon its strong agents near the beginning of the game and it does not raise the stats as high as it would normally
