I think people will overlook stupid things if they ' re traditional . We ' ve had new rt 1 common Pokemon every generation , it ' s just how it works . But BW pushed it too far I ' d say and was the only generation to push it that far , so it stands out like a sore thumb , like how XY and SM have been doing too much in the opposite direction , favoring throwing in old , seen and done Pokemon to excuse a small number of new Pokemon . I feel like Gen 3 and 4 struck nice balances , particularly in their usages of Pokemon from previous generations that didn ' t get much love , eg . making Murkrow , Skarmory , Misdreavus and a bunch of other Gen 2 Pokemon available and viable earlier on so people remembered they actually existed .
