Korence, what I don't understand is that you're the only person (excluding Yami) on this forum who says this game is hard. It is challenging, yes, but it's not over the top impossible. I find coming from behind to beat your opponent in a close battle is much more enjoyable than just straight out sweeping all 6 of their Pokemon, and I'm sure many here do as well. I guess it all stems from having competitive experience.
As for "not having the Pokemon for it", I had always thought Trubbish was (excuse the pun) rubbish, before I played Reborn. He is now one of my favourites. The game forces you to get to know and love some of the more unheard of Pokemon and that can only be a good thing.
Also, you should really give competitive battling a go, it's really fun and it'll help you improve!
