Welcome back to the Vault! I played a 1500 point game of 40K with my Grey Knights on Friday against the new Eldar. And got utterly battered. It was an enjoyable game but I made a lot of mistakes, starting before the game with poor secondary choices, continuing in deployment and then right through the game.
There were some poor dice rolls (at one point we worked out I'd done more wounds to myself via Perils than I'd caused to my opponent's forces), but ultimately I played like a muppet. Back to Initiate training for me!
