Liereyy just made a mistake by walling his ranges (& vills building them) too late. Nothing to do with the map. Civ wins are legit wins, it's part of the game to pick the right civs. This wasnt random civs. Liereyy's biggest weakness is late game raiding. He sometimes notices it way too late. Overall I think Viper has better map awareness, Liereyy better micro (sick skirm war, didnt even know it was possible to out micro equal army so badly). I don't see Liereyy taking the number 1 spot any time soon. Maybe he is as talented as Viper (or even better) but Viper has one massive advantage. He is a pro. Liereyy is not. Liereyy has school, Liereyy might even work. AoE2 is a hobby for Liereyy. Viper has other hobbies and is a professional aoe2 player during the day.
