It might be a good idea to include teams of two in the 3v3/4v4 ranks considering how many teams of two mostly play 3v3s/4v4s.
I just counted and in the top 50 2v2 allies teams, there are ~20 teams that mainly play 2v2s. For axis, it's about 9 (this number drops to 4 if you only consider the top 40).
