"The Maines were maybe a bit over-powered. I think in the next game I will take away the rule that they can ignore wounds that don't kill a model and have those wounds stay in place. I think I will also boost the size of the Ork infantry units to 15 stands per mob."
Don't know about the Maines, but the Marines really done me in.

Actually, I wouldn't go to(o) quickly making that first change; it was very Emperor's finest. Bump up the ork numbers a bit, but if I ever actually use tactics, being sure to try and concentrate on smaller groups of the hoomies might be sufficient to turn the day. A wasted 'wound' out of every three or five is frustrating.
A wasted wound out of 21 is just amusing.

Of course, the same can be said for the fact that the Marines were fully deployed while the Orks had reinforcements. I know it's a magic term, but does mean force concentration is even tricker, especially with random, on-edge placement.
