If i read that correctly somewhere in the internet, the increase through morale etc is 10% per rank, so at max +-50% movementspeed, attackspeed and damage?

I just looked it up on an old screenshot.

1 Rank Physique = 10% Movement Speed
1 Rank Morale = 10% Damage Output
1 Rank Concentration = 5% Attack Speed.

The same if the ranks are decreased.
