Of course the refresh is up for debate. I obviously do not know how drastic the change may be but Subaru has surprised me before. As it is I do not think that the front is as aggressive looking as it should be. The lights position is too far to the edge of the fenders and subdues the flare of the fenders. Had it been like the 2011-2014 I think that would have looked better. All subjective opinion, of course.
The wrx wheels are hideous but can always be replaced. The back end/ diffuser doesn't do it for me either.
So I have some hope that a refresh might address that. For the lights tough I don't think it can be addressed unless they flare even more which at some point would look like they're trying too hard.
