Props for creating an ability as flexible as this. It's not an overly simplistic approach to walls as we've had in the past, which is what makes it so versatile. I could talk at length about its applications, but there would be too many to list. It's as if you had several abilities stored in one. The concept is well thought out and execution is mark-on. Plus, the fact that it's so configurable is cherry on top. For me, that makes it one of the best addons I've come across in a long time.
