Kakashi becoming Hokage was fanservice nothing more. The sad thing is while it's bad enough that Kakashi becomes a Hokage, it's even worse that he doesn't actually do anything meaningful as the Hokage. Everything he did in the Last could have easily been done by Tsunade instead. So it really seems pointless to have him be Hokage other than to cater to Kakashi fans, but the funny thing is Kishi and SP ended up pissing off Kakashi fans because he just isn't given anything to do as the Hokage. I don't know what they were thinking honestly.
Try and count how many TS we got in two last chapters and novels/movie.
