Thanks CremeBrule, appreciate the kind words.

I forget who pointed it out, but back when Sith were first introduced it was said that the reason the "Big Time" where so pricey was because of their power AND because rarely did you ever see more then 2(max 3) Sith Lords together at a time, Revan+Malak, Nihilus+Sion, Bane+Zannah, Vader+Palpatine. Not saying it's the rule of 2 in SWM form, just something that appeared from the start of their introduction. Making a 40pt Nihilus, personally, makes absolutely zero sense to me from both a game standpoint and a character standpoint.
There is many pieces you can have to be army builders, and for instance just have a generic piece with low end Life Drain/Soth Hunger powers. There is no shortage of characters in the Star Wars universe, no need to downgrade poor Nihilus to suit the role of Army Builder. I would love to make a cheap "Sith Sorcerer" piece with a lower version of Nihilus powers, just say the word.
