I can't have fun with Vayne anymore

I have been an AD main for about a year now, specifically a Vayne main , yes i know i know...let all the hate out. I'm not the stereotypical vayne main though, i don't believe i can 1v5 constantly or that i'm God, in fact these days the trouble is to 1v1 anything at all. i'm not your average toxic player that plays 50 games with a champion and calls him self a main, or experienced, i'm the kind of player that has no talent at all and has to try 3x harder than every one else to do well in this game, but i will say, i am officially the 3rd summoner with the highest vayne mastery score (currently) in the world, and 2nd in NA. I don't say this to brag, if anything it makes me look horrible and fucks with my self esteem, considering i have only ever gotten as far as gold. I find my self in a state of discontent with my main, i feel like my experience counts for nothing in lane, no matter what i do or how stupid the enemy seems to be, you seem to always get out traded as vayne. I get that she needs to have this bad lane phase, and that this is the theme Riot has going on for the champ, but this has become SO MUCH MORE apparent this season, with a early to mid game meta/focus, champs like tris getting crazy reworks, or graves or mf getting ridiculously buff, it feels like every time i'm about to Q up, i cringe knowing my lane is going to just be utter hell and i will probably also get camped, cause every one knows how easy it is to kill her early, and how hard it is late. I also rarely see the enemy Vayne carry, and i can see that the skill cap needed to learn this champ is much higher than people will ever give it credit for...i would not mind tooning her late game down a bit, and buffing early mid a tad, the champ just feels weak, like my success rates with her have dropped so dramatically it's not even funny how often i lose to new tristana players, and it's getting embarrassing. The meta is just shit for adc's right now regardless, there's to much CC in this game coming from everything all the time, building qss never helps with shit, and if that's not enough assassins are just beasting all over carries, like LB 1 shoting me or annie, the entire game is perfectly normal and balanced? it's just not fun to play as an AD anymore, not just vayne, i don't have much fun with any of them because my success seems to be dependent on jg presence or lack of it on either side. Having to stall a game every time to the 40 minute mark not only gets old, but it's also unreliable regardless of skill.
