I hate players who only play on one map with one civ and use a cheese/ op exploit because of lack of skill. (Honshu Mortar ship rant)

I knew I shouldn't have readied up when I saw a specific map chosen that wasn't deccan, texas, or another semi normal map. He was a noobie player who I quickly destroyed with skirms and ruyters. His TC was down and his military prod and pop. Then he bombarded my base with navy, whatever i have tons of spare resources right? wrong. There are no areas on the map that can not be bombarded, so i could not build a new tc, farms, or chop any wood. so he basically only picked this map, to cheese mortar ship distance, to make it impossible to win. On top of this he kept saying haha in the chat and teasing me saying this map is so" fun". Now in your backseat driver chair you may have thought , build a navy!!! I had until he destroyed it as i could not catch the mortar ships before they destroyed it, and the ships kept destroying my docks. I also ran out of wood testing the distance of the mortars. Honshu is horrid.
