Are you aware that they cause large amount of drag where they meet the fuselage? The E.V/D.VIII had great performance with only a single wing due to the massive reduction of drag. And why are you assuming that a triplane has more wing area? The D.VII has more wing area than the Dr.I and it's a biplane. Not to mention all the retarded STOL stuff that bush pilots get up to in planes like the super cub, which is also a monowing with less wing area than the Dr.I.
