Actually, having someone call plays can be completely busted if a few teammates listen to the directions, and the plays are actually solid. If even 1 other member of your team cooperates a play with you, the chances of it succeeding in solo queue shoot through the roof.

Obviously, don't assume everyone should listen to you all the time, pay attention to plays someone else calls, don't spend too much time dwelling on bad plays, and if the plays backfire because they were bad, don't call them. But in all other cases, it can be the key to winning a game people thought was lost.
