The "matching" does not appear to be working, with very unbalanced teams, and the range of ranks for a particular battle is too broad. The screen shot is just a sample of what I've encountered today - 2 Legends, 1 Field Marshall, 4 Marshalls, and 2 Colonels up against 2 Generals, 2 Brigadiers, 4 Colonels, and 1 Lt Colonel. I would not have picked this battle myself - not fun at all.
