Thank you for your comments and constructive criticism, all appreciated and noted.
What I wanted to reflect was the expedition being led by capable and fearsome Generals, this is a raiding force and should be well coordinated and led. The high loyalty is there to stop them from turning rebel and spoiling the game perhaps, its not a true reflection of their undying loyalty to the Witch King (which as you pointed out is not always the case). In terms of 10 stars and the likes, perhaps rare for a TW MOD, but in Warhammer? Mighty generals leading mighty hosts are not an uncommon sight, so again, the higher stats are there to represent the force being well led by generals who command respect and the nature of the expedition being on foreign soil, surrounded by enemies.
What I will do is leave them as they are, once the community has had the chance to play the MOD, it can be looked at again and re-worked if needed/requested in a patch or a V.2 for example.
Thanks again for the comments
