After playing many ARAM games on seems I now know somewhat how where to position myself in a team fight. Since I mainly play tanky bruisers I know when the ideal time to initiate is. As well as when to dive into the back line. I am still working on my peeling however. Sometimes I just look at my ADC die while I am still tanking or getting to thier backline.

Every other Role I am still working on. My ADC mechanics are HORRID and my fingers are to slow to assassinate someone.

So yeah. Many games of ARAM have helped out.
