surprisingly to me, there are so many ork players that just don't use the boyz.
I myself play with 1-2 smaller groups of Choppa boyz, this is just because it is good for claiming areas in my opinion.
If you want to play orks, you just have to find what fits your bill!
I say to hell with efficiency, orks don't plan, they just fight!
anyway, this purple ork recommends you to have a good day!
