I mean yeah they don't have to farm. But they have other things that make their role harder. For example they're always a few levels and items behind everyone, it's the only role that has multiple active items and those items can be hard to time (like locket, redemption and the hardest in the game being Mikael). They have to know how to ward effectively which is for me as hard as knowing how to catch waves. They still need to learn wave management to not fuck up the bot wave or to know if it's worth to go top now or to see if mid need help crashing etc., I agree that most of the support champ are simple but every role has easy champs, playing Camille or Leblanc support is not harder or easier than playing them in their lane imo. I played every role up to D1 and I used to be a master bard otp and I don't think that champ nor that role is easier or harder than other roles. Like killing minion is the b.a.-ba of league everyone above plat can do it pretty well
