August not being able to harness Dragon Slayer attributes is an understandable reason why he avoids Acnologia (but at the cost of undermining his standing vis-a-vis Irene).

But if August can harness those attributes and yet he would still avoid Acnologia, that only raises the question as to how exceptional Acnologia really is among the various dragons and dragon slayers (guaranteeing that his defeat would be really really ridiculous)

It could still play out either way, although the former scenario appears more plausible if only because it doesn't inflate the power levels too much.
