there is.
wayyyyyyy back in the days of beta and early retail, leveling up would result in seeing what stats were increased (just like it does now) only in addition to str and stam and all that, it showed your class "skills" as well. for every level you attained, you gained 5 levels in each of your class "skills". for a druid, these skills were restoration, balance, and feral combat.
the feral combat skill is the one that determines all the melee stuff that happens in feral forms, and it is always maxed at 5*(level), 350 @ lvl 70.
