It is definitely more wideranged now to the previous lvlings I had. Back then I rarely saw 1 and 2, now for me it goes the full range from 1 to 4. But there are stats like resolve fati and init that getting the higher grades all the time in my game while the attack and defenses getting mostly the lower ones. But, and it is a big but, playing at normal with low end backgrounds even with lower fighting stat increases there are not many things that can seriously challenge my team. Maybe the stat increase range should be dependant on the background so a warrior like guy gets more into fighting skill, while a monk more to resolve etc.
