I don't see what purpose a stat minimum or cap by level would serve. If someone wants to train their stats past their level, I say more power to them. If someone wants to neglect their stats to level up, they'll figure out the error of that soon enough.
Some people like to jump in levels and use the energy gains to catch up in stats. Some people like to grind away at stats then level up. Either way, I don't see why it should be decided for them how they play.
