Guys this is a Beer and Pretzils game not the Fing Olympics calm down. Yes some scenarios may favor others more. Deal with it. You are working with a partner, one of you can be more "assulty" if thats what you are worried about. If i could I will bring a box of Pretzels and Beer to the tournament. Sadly 1. There will be minors, 2. I dont think Derek would like alchahol on the premesis.
40k is a game to paint models roll dice and have epicness happen. Win or Loose you have a drink and talk about how awsome a game was. If your going into this thinking you need to win like this is the Olympics then dont come. That attitude will ruin games and there will be no tales told of "how awsome was it when my Veteran Sergant totaly uppercutted that Carnifex for the kill?" no instead will be, "wow that kinda sucked to many people were to worried about winning a little soldiers game." I have been to many a tournament when people were to concerned about winning and not having fun, and you know what? Its been a year and a half since I have been to a tournament because of it.
In short stop acting butt hurt about your army and just play and have fun.
