I've got a lot of lootas (I play Deffskulz) and have to rely on them since I recently use Zhadsnark as my warlord, which means no Mek Guns. The problem I have with lootas is that in a Big saquad I lately roll poorly on their D3, so I get 1 shot most of the time. I recently saw this list
https://www.frontlinegaming.org/2015/11/15/da-orks-of-legend/ and decided to ty out
MSU Lootas. In theory if you use 2 CADs you get 6 5 man units, which means the same amount of shots as 2 15 man squads. But there are some pros - if shot at, you will loose 5 lootas at worst, you gan hold lots of objectives, you can balance out the number of shots. Only problem is leadership, but loosing 70 pts isn't ruining the day. Has anyone tied to use small units of Lootas?
