This has been a very interesting topic. I personally think they are fine the way they are, however, in my opinion two changes should be made.
First of all I think they should have an extra attack. These guys are veterens and men who have "...accomplised incredible feats of arms before their commanding officers". Let's face it, these guys are the best of the best. If you read Grimblades, even sergeants have great respect for them. If a sergeant gets an extra attack then these guys should too.
Secondly I agree with a lot of people; they should have a banner worth up to 50 points.
Other than this I believe everything else is perfect. The points cost should stay the same if these ammendments are made, otherwise it should go down.
Now that fear isn't as potent they stand a better chance of facing whatever the enemy can throw at them.
