Fix'd. 

Here's my more formal proposal for his leader traits:

~Champion of Mankind: -10% to losses against Gorrikans, immune to horrifying effect. 
~Roman Emperor: -1 to rout rolls, including pre-battle rout rolls. 
~Legacy of Alexander: +1 to enemy rout and pursue rolls (assuming those are negatives)

Edit:

YAAAAAAY GO JOHN!
