Its not hard to balance with noobs, just get another noob
True enough. I get most of my losses in two situations: (1) strong player (say, doggu, Zen_God, etc.) + me + noob vs 3 decent players; (2) 'overrated' players on my team (I have a list of players I won't play on the same team ever again: they all have good stats, are experienced and are nice guys, overall, so I won't go public with it -- however, in my experience, they either feed like crazy vs real top-tier guys or do not understand basic game dynamics/have low map awareness).
However, I see no harm playing pro + 2 noobs vs pro + 2 noobs or 2 pros + noob vs 2 pros + noob. Especially if the pros are more into educating the noobs, than into shamelessly farming them. Such games are somewhat unpredictable (I've seen some cautious/unkillable noobs, for example) and are decided by the relative level of 'noobiness' of the noobs attached to the pros, but they are fair as far as balance is concerned.
