Still, isn't the whole point of you going on a journey to become the Pokemon champion by defeating the E4, and getting stronger along the way? What's the point of it if you could just go to the E4 at the start of your journey and have them just 5 or 10 levels above you, and that would be the exact same if you did travel through the region legitimately?
I didn't found them at all ;) They were made by LaZ with special premission from him I was lucky enough that I could used them in dark cry: TLOG.
Oh and about the automatic level increase, It doesn't sound that horrible. The main idea about is that I don't have to pay attention to the pokemon level on each route! This routline automaticly counts that for me.
Even, to more specific, the trainer's pokemon will be decreased with 2. Only the gym leader has +5 and the team rocket members are always equal ;)
