I play Astra militarum and my friends collect CSM and Orks. We usually play 1200-2000 point matches and my army list and play style is not something I would describe as a competitive list. However, almost every game we play the game is decided in round 3, and they are basically tabled in round 4. It's frustrating for everyone when we basically know the outcome before we dedicate a day for our games. My opponents has tried changing tactics, bought new models to counter mine, they get to set up all the terrain (we have a lot) etc.

We are all dumbstruck by the amount of bodies and heavy armor I can get for the point value we are playing, and we agree that it feels like we are playing 1500 vs 1800 points sometimes.

It has gotten to the point where one of my friends has given up entirely, and the other one might be up for a game every other month or so. When we do a post-battle analysis we agree that my opponent didn't make any tactical mistakes, or had a bad list, and i would probably make the same decisions on the battlefield.

Are Astra militarum just the rock to the Orks scissors? Are there any particular units my opponent should use or avoid using vs AM? Does anyone else experience similar results with these armies?
