In that way he will pick up SPPs faster and later be able to pick Pro and Block. With good assist he will be cracking skulls!
The back side is that he will fail more bonehead rolls (without pro that was my first skill choice before). It will also mean longer time without block

Also, can this ogre use both mighty blow AND piling on the same victim? (+5 on armour roll AND +1 on injury roll).
Or is it one or the other, not both?
