Personally, I hate level grinding in any Pokemon game ever. It takes too much time and I'd rather focus on the storyline that training. It's so boring. When I played BW and B2W2, training took forever and I hated it, but I couldn't just run through with one Pokemon like I usually would because that was too hard. What I want Gamefreak to do is have in-game cheats that you can turn on/off, which would work for me because I rarely play Pokemon Games fairly. It takes way too much time and I am way too busy.
