Thank you for the feedback! It's intentionally written that way, which is why it costs an attack to perform the Nullification move, and why Nullification can be done only within the Nullifying unit's range. So, for example, a unit with only the Nullifying Modifier (2pts) would have to close to within 1 inch with a single enemy unit first and give up its attack in order to use its Nullifying Modifier. In larger point battles, you could have units with Ranged x3 + Nullifying + Acrobatic that could be devastating, but they would still only be able to affect one unit per turn, and only by giving up their attack. The enemy could just make that 6+ point unit a priority to destroy as a strategy.
