>>28493493Trainers sometimes use items, switch out, and have more than three Pokemon in the earlier games, for starters. Veteran Shaun in that B/W cave is literally a random NPC trainer that will give you every bit as much of a fight as the Champion and god it was so wonderful to just run into a strong trainer out of the blue.
Literally no one in Kalos other than the Champion and maybe your Rival has more than 4 Pokemon for the entirety of the main playthrough of the game -- a game which also pushes you to use hyper-powerful Megas, yet gives them to all of around three trainers, one of whom is a tutorial battle. In addition to your Pokemon getting crits every other turn and extra exp from Amie bonuses, or even HAVING A FREE FOCUS SASH if your affection is high enough. And unlike the exp share, you can't just turn that shit off.
Gen 6 was just easier in every conceivable way. Free high-BST Pokemon, free Megas, exp share shenanigans, Amie shenanigans, stupid AI, weak teams -- and yes, Pokemon has never been a challenge, we get that, but fuck man, XY is notably easier even when compared to the rest of the franchise. That's the complaint. People don't want Dark Souls, they just want the general standard of difficulty they're used to. That's not much to fucking ask for.
