I did give a short overview. Gondor was better through all the game. He took iniciative in early and kept it the whole middle game. He entered late game with huge pp advantage. Rohan was just building horse army and losing big pp in few encounters they had. If Gandy would make 1-2 WB on EW, he'd be L10 and the game would turn otherwise. But he felt and one GC finished the castle.
