I didn't say "in one attack", I said he could, since he doesn't really give a shit about humans, also the roar is the most basic of techniques and Mashima lacked the creativity at the time to give the 7 dragons anything other than that. I was just making that statement for effect since Makarov was also being overly hyped. I am well aware that we know very little about Acnologia, which is why this is all speculation, so saying he is weak or strong in this argument isn't really fruitful.
