Did you even test this build? 2 cta3s only give +5 to bo therefore it's a total waste. I would recommend a cta3+hoto giving you the maximum of +7 to bo.
As frater stated 1 point in command is enough.
If you are gonna do pvm with your barb then:
Usually bo barbs are used as wc barbs but i personally don't find them that good, I'd recommend maxing whirlwind and 1 point in concentrate. To help out in baals you might wanna use 2 botd bas since they have nice mana and life leech but if you are going for damage use grief+beast bas.
Also any barb should get a minimum of 40frw from the frw skill.
1 point in natural resi is not enough, usually go for 3-5.
Leap is also damn useful even in pvm and a couple of points there would be good aswell.
Edit: for pvm maxing iron skin is useless since monsters have low ar and if you need a tank use storm and max block. The best tank is beast+storm with max block and in bear form since you get a massive life increase.
When using max block don't forget to walk cos running decreases block to 25% on any build. It's pointless to max block and go around running cos you basically take away your advantage and also decrease your life.
Edit: also this build will not be able to hit anything in pvm since you get about 4k ar, recommended ar for pvm is 10k.
