Maybe its clear, but totaly unplayable. If you look at the logic of the bombardment its ridiculous that one guy steping forward can stop it. We have that clarification with LOS to the template and it seems playable.
Well, this is one of the cases when we followed the original UWZ rules to the letter - the rules require FO to have LOS to the target point (not template) and state that models block LOS...
The rules for fire missions clearly indicate, that they were intended as an area-denial weapon*, used to prevent the enemy from claiming advantageous positions (or strategic points, like in the case of our tournaments). They can still be used in this capacity - it just requires careful calculation and positioning. We did not want to change the FM rules in any way that would make them mass-destruction weapons - especially since Dark Legion would be boosted by any such change much more than corporations (better FMs, better FOs, Force Commanders are easier to field in Legion) and it does not really need any additional advantages.
* - low maximum range, the fact, that aiming point must be no further than the closest enemy model etc.
