But that's a small price to pay for having an excellent champion when its all said and done.
Balance should never, ever be given away for "fun" if a GOOD champion/hero designer creates the champion.
See: every MMO ever (hint: the MMO dies out or everyone starts playing that class)
Also, another example is the fashion industry where if a piece of clothing is fashionable and nice looking, people will put their eyes on it. However, if the piece of clothing is uncomfortable, people will tend to stay away from it.
Because his champions are "fun" does not mean that it is helping this game out in terms of design, rather it is hurting it by taking a huge dump on the power curve, affecting the game in a negative way.
