faraday tensor does describe in a single way the is an antisymmetric tensor having six independent components.However one can write maxwell eqn in a form similar to dirac eqn in which E and B are used in some form like E+iB. Although those potentials can be combined to called four potentials but it is just a way of simplification and covariance.
