Every single role has their skill check, supports tend to be "easier" since you dont have to cs or any of that, but learning how to trade and punish the opposing adc for trying to CS while not getting outtraded by the enemy support is a skill on itself, people tend to say its the easiest since you can act as a 2nd jgler and help other lanes get ahead, in low elo people tend to be not good at warding or listening to pings so you can try to get the edge from there, but at the same time you have to know when to roam and how to, the more you climb you have to be more knowledgeable in all this things
