A lot of 7DII users will be wildlife photographers. A lot of wildlife is most active at dawn and dusk. I often find myself wanting to take photos but getting 1/50s at ISO3200 and wide open. Improving the noise characteristics which each generation of sensor and thus being able to expand the available ISO range gives a real and important improvement in wildlife photography. It's the difference between being able to take certain photos and not.
Not just wildlife.
What happens in one sensor or camera eventually translates to all cameras. I'm primarily a landscape photographer, but also shoot wildlife and other wildenrness subjects because they all tend to occur in the same places.
As a landscape photographer, I make huge prints. When shooting wildlife, I often need to crop, sometimes fairly heavily. These call for high resolution and high pixel density sensors. Dusk and dawn produce the best landscapes and are also when wlildlife tend to be most active. This calls for better dynamic range (since higher DR at ISO 100 when shooting landscapes also translates to higher DR at ISO 12800 when shooting animals in the shadows) because the lighting at these times tends to be very high-contrast.
Canon has delivered better and better AF and weather sealing over the years, but so has Nikon - their top systems are equally good at tracking moving subjects. On the other hand, Canon's resolution and image quality have barely improved since 2007, to the point that the current Sony/Nikon sensors have two and a half stops more DR and higher resolution than Canon, and Sony's next sensor will have over twice the pixel count of Canon's best.
The only reason I haven't moved entirely to Nikon is the existence of Canon's tilt-shift lenses (which I use on an A7r). For every other still photography application, Nikon either matches Canon (where IQ isn't critical) or vastly exceeds it (where IQ is critical).
