If you ever hit rr70, you can try this

With Stop Hitting da Runts you will pretty much have infinite AP, and if you need even more, always use your Get 'Em ability. And of course, use Da Biggest bellow for loudmouth proc for most dakka and for AP.
If you don't feel like you lack AP (which you probably will cuz of Can't hit me), you can take Not in da Face or KD. You will be an immensely annoying tank. When you start getting focused just pop CHM and you'll be good really. I'm trying out this spec for soloing and small scale mostly. You are not very useful in a warband without the aoe snare though, so I'm still thinking about it.
For renown points, max out your block
always, then at least lvl 3 deft defender. Other stuff you can put into stats you feel like you need the most. Since you will be pretty tanky with your CHM, you can spec for str. I wouldn't recommend stacking str talies. I never like that. BO can deal very nice dmg and has lots of utility even if you're at 400 str. Anything above 600 is an overkill to me. After all you are not a dps class. But with THC and loudmouth you will see your damage is very good.
But enough of this high rr stuff. If you're at 40 rr, you can use this
http://www.ror.builders/career/black-or ... 00,4496&t=. This is your aoe 'I wanna hit everything!!' build. Keep your snare up all the time, and spam away your Waaagh!. Use the block tactic of course. You can also take loudmouth here, and wounds or toughness tactics. Wounds is best for RvR. And take morale pump tactic if you wanna do some really big aoe damage.
