Since I do seem to remember rosters with more than one Big Guy on the team list but there was a "One Big Guy Only" rule.
At least that is what I can tell from my foggy recollections of the games past.
I know the Ogre teams can field up to six of the Big Guys, otherwise it would be a strange Ogre team.

Since I can't seem to find this rule in the CRP now, is it safe to assume that Chaos Pact can field all three Big Guys, Ogre, Troll and Minotaur, at the same time?
I'm pretty sure the answer is yes but I just wanted to double check.
