The difference isn't 8%, the gap is a little higher imo. Since you not only need a crate within reach but also a weapon with a decent explosion radius in it. I don't think adding zooks and/or nades is going to help the scheme in any way.
For some reason I can't watch any of the past streaming videos. Was gonna watch Mablak vs Dario since I couldn't watch live, doesn't seem to work for me.
