I'm glad to see that this thread is gettting a lot of action : )
Yohosh, you make an excellent point.. I never thought about that..
And people who are saying, underlevel your Pokemon and make challenge runs, I believe you are misunderstanding the point of a difficulty choice. My point was, I want the games themselves to be more of a challenge just playing through in any manner, but I understand that there will always be people with less skills than you or I. The thing you seem to be talking about is grinding up to smash trainers into oblivion, which is really all you need now. In my mind the harder setting should require more stragety to defeat, providing you with a more realistic journey, where you are a beginning trainer in a world of champions and will be treated as such. Where as now, you can grind and never face a challenge again by using simple power moves.
