-snip about balancing-
There are always pokemon like that. In the first gen, the bug pokemon were considered 'Level up quickly for high power at the start and low overall power' and a Gyarados if you could be bothered grinding to get one was almost required for your team.
In gen V, there's Audino who isn't terribly strong overall, but has a move 'Heal Pulse' that heals a target, and it has an absurd amount of EXP for its level.
