Adrenaline Rush will eat at least 5 points from Light as a Feather which will result is a veeeery slow 2H War. Initiative is very important if your focus is not very defensive because you will effectively trade the toughness offered by the high tier War skills for hitting power - but you won't get to see that hitting power very often if you take 4-5 heavy hits before your fighter's turn even comes. If you don't have a slave with 90-100 Size, better skip that skill.
