It will deal the same damage as 4 amcs actually (against shields). Since the ion block doubles the damage done by the amcs. So it actually take less energy/space and does more shield damage then plain amcs!It doesn't matter if the blocks are weapon, support, or effect blocks, every block in a weapon group adds to the weapon's total damage output. A 1/1/1 AMC/AMC/Ion will deal as much base damage as 3 AMC blocks.
