There were three Grey Knights armies and Michael Sanford's won Best Appearance. He also came in three points behind me and if he'd have won that fight with my biker nob then he''d probably have the Best Overall trophy - it was that close.
One thing to remember is that the battles are SCENARIOS. You don't need the perfect army to defeat all comers, or rely on a specific unit to be competitive. You should have seen the look on my face when I realized I'd have to roll a dangerous terrain test for EVERY ONE OF MY ORKS! Yikes! I wonder how many dice I rolled in that game. Needless to say, what the Tyranids didn't kill I ran to death....
We were all happy, so that's what's important. No need for white knuckle gaming.
