What to do against "tuning out"?

Hi everyone

I am a rather bad player and while I have no interest in ever playing ranked I would still like to improve myself. Thing is, my main problem is that whenever there is action on the screen I kinda "tune out" and all characters blurr together into one big mass and I am unable to really process what happens and where the champions (including mine) are. This seems to be limited to LoL only as I don't experience that playing shooters or other RTS games. Has anyone had the same problem and how did you solve it?
