In all honesty, I was not aware that the D610 had focusing issues. Or at least, I hadn't read any information to that effect.
As aforementioned, it is not an issue but a weakness compared to the camera you already have and the the kind of shooting you intend to use it for.
Here is a side by side comparison of their focus to shoot speed. As you can see, the D7200 is almost twice faster than the D610. And as also mentioned previously, if your good at manual focusing there would be no difference between the two.
As marked by the yellow circle, it is worst when using all the focus points, which usually is the best option for something you expect to be moving unpredictably all over the scene.
