This sadly... They're also a lot more tactical depending on the mode. I know a lot of people dislike 24 man Secure but some of the most fun in PVP I've ever had was being shuffled into the 24 man variant of that map and working with my randomly assigned team to pinch and generally harass the other alliances. It feels like good play is actually rewarded in a 24 match, where as good play really isn't going to make much of a difference in the 72 mans if the rest of your group or even a small portion of it are idiots.
