Was the range of FoF lowered at some time? The last time I played WW was in MoP, and as I recall you had a fair leeway with the range. It would hit and stun enemies slightly further than regular melee range. Now in Legion it feels like you have to be right at the feet of your target for it to hit. Not an issue with single targets, but against several enemies I'm noticing that very often there's targets that aren't taking any damage.
Looking through
http://www.wowhead.com/spell=113656/...fury#changelog I'm noticing that at 6.0.2 suddenly the tooltip says "melee range", whereas previously it didn't say anything. Is this when it happened?
