Where's the "Both" option? Because I don't see any reason not to have both. I wanna rematch trainers, but I also want the option to get some more rare Pokemon that lurk in the grass.
I agree with this.
But more importantly, I still don't understand how anyone ever felt the need to grind in 5th gen games. I literally never went Audino hunting (or grinding of any kind til post game) and I was almost always overleveled in both White, and Black 2.
As I said, I want to know which you would choose if you had to choose between the the 2. Also you being overleveled is probably because of the new leveling system. Maybe I play differently, but to me it seems that not fighting anything but trainers and gym leader will not make you overleveled, just average.
