Not counting the promos. Why don't the English sets have the same cards as the Japanese sets? I can understand the reason for Darkrai. (Not been released outside Japan yet) But appart from things like that, why can't they be the same? An example would be DP4 and DP5. In Japan, there were 6 Lv.X in each of those sets. In English we get stuck with sets with 2-4 differant Lv.Xs. In Japan's DP4 (And probably DP5) you got 2-3 Lv.X per box. While in English we get 0-1. As for the non-Lv.X. DP4 had 135 non-Lv.X cards. In English we got 102 cards. This seems to be causing a "filler set" every year. So my question is: Why can't the sets be the same? Is there any real reason?
