Lets take another example: My last loss before that was with my tomb kings against warriors of chaos. In this match I was basically cut down and destroyed. Warriors of chaos are simply so powerful in combat that once they got to me I melted away like nothing.
Was my deployment wrong? No, I had out deployed him. Was my movement wrong? No, my moves actually ended up with me wiping out a unit of 12 knights do to overrun. Could I have supported any better with magic or shooting? Not really, I was already running a casket and double skullapult. In the end combat had to happen and even tomb kings supported by a king wasn't enough to top his warriors. My solution going forward is to focus my points on units that are better in combat.
