So I just beat the E4, N and Ghetsis. I've traversed into the post-story, and I'm finding that may of the NPC trainers have Pokemon level 65 and over.
My party is in the 50-56 range, so how in the hell am I supposed to compete with these trainers without grinding on wild Pokemon? If I'm not missing something here to train my Pokemon to a competitive level, then the developers kind of screwed up, considering every guide I have read says my Pokemon should be at least level 56 by this point. What's the deal?
