It's nice getting more EXP. from higher leveled Pokemon, but level 60-70 was a disaster. At least level 80s had the Black Tower and White Treehollow.
The only series that I've seen this EXP. system work well was Paper Mario, and only because every level up required 100 EXP. --- "Cheating seems to be a relevant term only when one is caught in the act. Otherwise it is viewed as intelligence, no?" - HK-47, Star Wars: KoTOR
