It sounds like Eeiu is going to help with mid rounding regardless of who our actual IGL is
Speaking from the outside looking in, your scan initiation should be either your IGL or a sort of midrounding secondary caller. The info they get from util is by far the most relevant type of info needed for adjusting with the preround call doesn't work. Not saying having a controller IGL or Sentinel IGL is bad, but i think if you were thinking of how to construct the perfect team, you would want your leader on that role.
