I was browsing through and fiddled a little about with army list and I noticed a few things in the Orc Marauders list that got me thinking.
The first one was that the Warlord seems to be worse at close combat than his sub-bosses A2 vs A3 seems hard to keep those sub-bosses in line if you can't beat them up properly Also noted that if you take a Energy weapon they all get reduced to A2 if I read it correctly? Still the AP bonus i probably worth it. However the Power armor Orcs still get the A3 with the energy fists.
Finally I when I read the stats for the Energy fist and the walker fist I got tempted to try to reduce their attack values and instead add Deadly to them, to increase their chances to rip through vehicles and similar. I guess that has been tested during the playtesting. How did it work out? Did it get to much the charger wins in walker vs walker combat?
