Ogres also have multiple attacks.
One of the things that came up with the local GW club trying to make a "comp system" was discussion of model limit vs. wound limit. The initial suggestion was a cap of 40. I suggested wounds, the counter was that Ogres couldn't get more than 10 in a unit at that point and won't have a battleshock bonus. But Ogres can do 6-9 wounds *each* (obviously, not going to happen, dice being what they are, but still can expect 2-3), meaning each one is capable of absorbing and dishing out punishment, and battleshock isn't as likely to come into effect considering it's modified by number of models removed, not wounds done. Add in the standard Ogre banner (even my skull banners will count as this one) that lets you reroll a 6 on battleshock tests, and it's unlikely Ogres will lose anyone to battleshock, unless you got seriously mauled by shooting or combat.
Other multi-wound units tend to have similar capability to dish out damage, and Knights and Chaos Warriors tend to have solid Bravery values.
