Interesting article... ill have to rethink some of my lists

Well, more like a different kind of list-building.

The 'probability pool' thing works both ways, as far as single die rolling steps go. Such as the armor save. Many units in the game will have a choice in options of either causing few armor penetrating wounds, or causing MANY wounds that allow saves. One way eliminates a step for you, but the other spams that same step at your opponent. Some might chalk it up to preference...

Take my bike squads for instance. Many folks on the internet would site my dual flamers as a terrible choice, insisting on dual melta to accompany the multimelta already present. Of course there's plenty of anti-tank merit in that preference, but what about the other stuff? Two meltas could maybe zap two more dudes, but they could get cover. So I find it quite useful to pile on the armor saves with the flamers.
(Though I am using Vulkan, so the TL-ing makes it a bit different.)

That's when many would insist that the flamers are flawed by their need to get so close. "If you can flame, you're too close to the enemy". What they fail to understand is exactly what MVB touched on in his article. It's about utilizing all the aspects of movement to advantage, minimizing their attacks and maximizing your own.

Some of this was made pretty plain to ya early on, Chris, and I'm sure you picked up on it quickly. How many times was it that you had CSM hop outta rhinos to take pot shots, only to get wailed on in return? Its about knowing when to commit, and also knowing that you can't rely on any unit to get the job done unless its committed to the task. We don't need pot shots, we need to "let 'em have it". But can you give without getting in return?

I think the example that MVB outlined shows a very common mistake players make. They go for the immediate half-ass attack, as opposed to waiting/maneuvering for the full effect. This happens especially when a looming threat is poised on the unit in question. Even vets fall for this one at times, likely under the auspice of 'do what I can with them, before they drop'.
