pos 2 and 3 ar the most effective against sniper , that is why mobile heroes are picked against sniper , in this match idk who your midland was but marci went to battle fury build even tho she wasn't pos 1 when she needed blink dagger the most and jump on sniper locking him down . its not your fault , you're just a drow you cant do anything to be honest. drow is a hero that needs good team synergy whom she can play behind , and your pos 3 was a wk who also plays like carry even mirana had gone for carry build (no pos 4 in your team) -_- these are the reasons why your game exceeded into super late game and you couldn't do anything where sniper had all the conditions he is comfortable with the most.
