Either you're doing this wrong, or you've been really unlucky! On a successful mob rule test (results 2-6 at least), you take D6 S4 HITS, not wounds, so on average (don't forget the t-shirt) you should take 1.46 casualties (I.e 1-2).
Yes indeed, I was playing it like the old codex as wounds, not hits. This last game I lost a lot less boys to mob rule.
As for the ten strong trukk boys, it works ok. I noticed no real difference in the game with the choppa/slugga boys. The shoota boys in my drive by truck still need the full 12 to be effective.
Waaagh! I'm struggling with the dex, but aren't we all? This is a new 3 CAD list, and I feel super beardy, but its really our best bet with 7th. Any hints/tips/tricks/advice, you know I'm down to hear it, why else would I post it?!
I have learned to come to grips with making the new lists using multi force orgs (detachments). It took a while for this old ork to figure out that the major change to 7th is the multi detachment list (and of course the cards).
So, like you, my list has remained about the same, broken down into multi detachments so I can take more fast attack choices, only now I have to spend more on HQ choices than I like. The pain boy seems like a cheap HQ, and I was wondering if I could just take a mek as an HQ using up the slot rather than getting one as a add on.
The other part I have a hard time choosing is which force org to use. If you use the one from the ork codex then your troops get hammer of wrath (sort of), while if you use the one from the rule book your troops can trump control of an objective. Since just about everything is scoring now, that seems a valuable trait to have. But, if you have large troop units like you do, then the pseudo hammer of wrath seems worth it.
One thing else I have found is that only your primary detachment gets the bonus, secondary and tertiary detachments don't get the special abilities, making you want to put the majority of your troop choices in the primary. (unless the rules lawyers at my local are reading it wrong...)
So, maybe you might want to split your grot unit into smaller units, put most of your 30 boy squads in your primary, and then use multiple small units of grots to fill out your other two detachments troop requirements. You may have to drop the three big shootas from the boys units, and the orderlies, to get the points for your four squads of 10 grots.
I have also found that the lootas are great anti air. Better than tank bustas, So, maybe in your tertiary detachment drop one unit of 30 boys for the full size unit of lootas. Of course I see you have your grot gun batteries, since you don't list what gun they are using, I would guess kannon. If you are making them traktor guns then never mind the advice on lootas.
Let us know how they play out. I may just have to convert to large units of boys in BWs. (does that mean the Evil Suns will disown me as I am using Blood Axe tricks?)
