Here\'s the deal. I now have my book with me so I can make some decent comments.
Wardancers die to shooting. so, for 14 points, you can get 1 extra attack, or for 18 points you can get the extra model, which will give you 2 extra attacks. ( Gotta love wardancer weapons) and an additional casualty.
You can\'t get a standard as it is not a choice.
The musician can be useful, If you flee, you will be rallying on leadership 9. However, if your wardancers flee, you\'re pretty stuffed anyway.
Wardancers need to make the charge, and you are going to have to be breaking units on the charge or holding them in place to get more units into combat. using them for anything else is going to be a waste.
