Aside from the Eldar I have one semi Army that I have that I don't use unless absolutely necessary... As in I have to be called directly by somebody in a campaign against chaos for me to even show up that are semi Army is a Grey Knight group, consisting of two Purifiers squads a Templar squad and just some normal unit squads. So my question is what is everyone's thoughts on actually having a Grey knight semi Army, would you think it would benefit you in a campaign or you like an acquaintance of mine who loves chaos to just freaking hates them..
You should look at the other subforums, this (and a previous one) aren't topics for general discussion.
