As your Character grows stronger, the enemies near Camp Bearded Rock and Camp Skull Valley become easier to kill. Its not much of a challenge to defeat an enemy with one hit now is it?
I propose we carry over an idea from FF-VIII. In FF-VIII the enemies gain strength as you do. this was difficult at times, but we may be able to salvage this system to make low level areas more enjoyable to high level players.
I do not intend for a Wharf Rat to be as strong as a Dire Rat so there should be a curve as to how much an enemy can be improved. Also there would be a limit to how weak an enemy can be.
If this system was used, the areas that are not for your rank wouldn't give you much experience points but still present an enjoyable battling experience. The areas that are for your rank would give you the same experience points as usual.
