I don't have an issue with it (and not because I'm using it). Sometimes you have to 'stagger' the unit to fit in terrain, or around terrain. Narrow your frontage, to maximise the amount of shooters to a unit. It does come with a negative, half move, and irregular, so no support. You have to balance risk vs reward.
However, I do have a problem that you can expose 2mm and the whole stand can shoot. In organised play, it might not be obvious if the unit is irregular or regular. I would be inclined to add a clarification like on page 37, for blocked charges... that at least 1cm of the front edge needs to be visible to allow the whole stand to shoot.
