team comp doesnt really matter until like.... 1850+ (or the equivalent of normal elos (ppl need to super realize this because fanatically adhering to traditional team comps at low levels is just stUPid often the best way to power elo or win normals is to do something unexpected and unfamiliar (its called metgaming the metagame WHAT NOW))

i've won ranked games in 1650s as mid jax with ap alistar top jungle yi and mordekaiser cho'gath botlane (who constantly needed ganks from jax mid but it was 0K cause I was smashing lux's face in)

also on the subject of vayne even if you fail hardcore at the start there will be a point during the game in which you can just attack move and autowin team fights believe me I know from experience
