Oddly enough there are more 3v3 games logged in the latest patch than 2v2.
I see that now on Coh2 stats (Legend). My thoughts were more that higher rank players may not be playing yet. People that would abuse this if it is a weakness.
Just thinking about the arty issues in Coh2, makes me hate Coh3 even more. Since it is painfully obvious it needed a "Recon here" button on the minimap. It just reminds me how the people making that game clearly never played it.
