But like I said it really doesn't matter no one brings it up in ITC tournaments also because of ITCs detachment rules you can pretty much do whatever you want as long as you are not come the apocalypse with someone. But what I'm saying there is no point in trying to fight about detachments.
Dude, you may have the old book and/or didn't read the new core rulebook about factions.
Also, it's not fighting - it's playing by the rules. Using a CAD Tau and an AD FSE (or vice-versa) is cheating.
