I understand and agree with what your saying Watcher.
Yes, the WR will always have the advantage of knowing his route. But it's the second paragraph of your post that worries me a bit. However I do have faith that Ian and his team will have "Balance" in mind while adding this tech.
My reason for confidants is....Ian in past Blog write ups stressed the importance of balance in Maddens gameplay. I guess maybe I'm still having withdrawals from something called "Wide open gameplay".
