So basically, if some guy is controlling three CVs, and I outrank him, I could take command of group 1, give up command, take command of group 2, give up command, take command of group 3, give up command, and then assuming he's not taken any of them back, go back and re-take command of all three, and hold them all? I'll have to give it a try.
It's really frustrating when some bozo with a high enough rank takes control of all the CVs and has them doing retarded things, and nobody's around who can take them away. I'd be perfectly fine with a strict one CV per player limitation, regardless of rank.
