I don't know...In
40k you'll see people being docked for taking special characters, or having special characters banned as well.
Not all the
DoC special characters are nasty...I'd rather have a regular Bloodthirster tooled up than the the special character one.
I think the penalizing special characters come from the mindset back from where special characters were opponent's consent only so there were defacto not tournament legal and you never saw them played.
Personally, I would rather not see special characters on the field...But that is just my opinion. There is a local Empire player that I like to give a hard time that he's playing a Vampire Counts army because he keeps on bringing Kurt Helborg back from the dead
