I am a hardcore tournament player who has played in Rogue Trader Tournaments from Salem, Oregon, down to San Francisco, Sacramento, Los Angeles and San Diego, California. I have also played in Jacksonville, Orlando and Tampa, Florida. Right now I am playing and living in Phoenix AZ, but the tournament scene is rather dead for a city of this size, so I might need to join a league.
I try to attend as many large tournaments as I can. Although the GW Grand Tournaments get a bad rap, I enjoy them, and my goal is to win a GT one day. Also I attended Adepticon in Chicago every year and if you are a fan of 40k, this is a must because there is no other event quite like it.
We all know that most armies win by dominating one phase of the game. They either dominate the shooting phase, or the assault phase. Yes, there are armies that are well rounded, and armies that are very durable, but for the most part armies win by dominating one of those two phases of the game.
So my question to you is can an army win by dominating the movement phase? Can you create a small and very fast moving army that can win a game? An army that can out-maneuver other armies, and hit where they want to, and then move on. Something like how a boxer can stick and move instead of throwing hay-makers, and instead of going for the knockout, just throw jabs at the enemy and win through finesse.
I was thinking about this type of army with my harlequin army. It is small and elite, but it is also very fast. I was thinking about building it around Jetbikes that can move 18" a turn and turbo-boosting 24". Add to this Falcons with Harlequins that can move 24"+12" with Star Engines.
Against shooting armies it will try to get to them in one or two turns, and then try to get in the middle of them and try to wreak havoc. For example a leaf blower-type armies do not like to have models in the middle of it wreaking vehicles, and then using them as cover. It operates by killing at range and taking out anything before it gets close. Especially if you can kill the transports in the shooting phase and assault the contents.
Against assault armies it will work by moving fast and hitting at the sides of the army so the other units can't support them, and taking out chunks by striking first, and striking hard, and then moving on and repeat the process.
