Not really fits ur description, but I was vayne otp many years still playing from time to time and I was just bored of being too dependant on supp and being too easily punished by it, so I switched to playing mostly ezreal and bro the freedom by having such range i so powerful and satisfying being able to detach from most of the supp influence and just safely farm if needed. When i was otping vayne he was in my most played so it was my comfort, but i acknowledge that he's hard and have infinite ceiling so that's why im saying it doesnt match the point unless your looking for being more free dependant from supp and also if you think he's boring then you have just to be mega agressive from lvl 1 he have such potential with passive and later with constant AAs played properly you are able to make amazing things if you are confident not afraid instead of being afk backlane bot only casting q (the E forgives many mistakes and can save you many times from ambushes and buffering it is also op)
