U really wanna set vamp to 5 or 6 points?
i dont like the image that i pay 6 Points for one unit what have to make suicide if the other regiments are down..
for 6 Points u could buy 3 Regiments of Skeletons or maybe 2 with Arkan Banner or Ptoleos Shild.
What brings a Wizzard what cost more than 33% or the whole army if he have to make suicide at the end?
4 Points i think are more than enough.
