I counted every thing (and still do via that helpful spreadsheet), so I definitely hope these emblems unlock at the end. 7 fucking hours of pissing about in the Red Zone. :lol 305 kills as well.
The one thing I noticed about going for the kills is that you grind in Act 1 or 2, but then you rack up another few hundred in the other acts anyway. It makes me wonder if grinding is actually that necessary for it. At least, on the 6 or 7 other runs you have to do.
