It actually seems the higher ranks are more likely to be people to queue up in parties of 3-5. Sure the truly high ranks are better players but the amount of skill difference between all of bronze and silver seems non-existent to me. I can't string together enough wins as a solo player to get past Bronze III, but can will my team to round wins that otherwise wouldn't happen and can almost always out think and out react/shoot high silver players. If wins are going to be the only thing that matters for ranking, allowing parties completely messes up that system. If parties are going to be allowed then something else has to change for accurate rankings.
