More Meaningful skill in League

Hello, I'm a Support main and mainly a ranked solo player. I have been playing since 2011 and began my ranked experience from Silver ranking in season 2 all the way peaking to season 5 D1. I wanted to post this discussion too explain my feeling of the rewarding and disadvantages of playing support throughout each season and the ability to carry games. Over the course of each season I feel as if each meta 1 or 2 roles have the ultimate carrying ability to win games. Currently my concerns are only certain roles are guaranteed to be able to carry the game and I am forced to sit in lane "hope to survive laning phase" because thats our role/position for a certain particular games. As this is happening the lanes that do have the opportunity to win there lane fail to do so and me as a support player don't have the power bases on all support champions to be able to carry the game until lets say after I get sight-stone/mobility boots. What I'm trying to convey is that it really sucks playing the best of your ability for the first 10 min of the game to have a small impact of 25% when other lanes fail. As a support player with 5 yrs of support experience I can't full show my experience because im being gated until a later portion of the game. What I would like to see is support players who have experience with the maybe 2 or 3 champions be able to carry the games like back in the day of thresh and alistar. Everyone know's of Mata's famous thresh game play, Wolf's Alistar performance and it showed how much they good carry games. A suggestion I would like to see in the game is what if instead of being gated abilities, such as lvl 1 on thresh getting flay, Death Sentence, Dark passage, getting all 3 lvl 1 and only getting ultimate abilities 6/11/16 this could open up different ultimate abilities maybe have different ultimate abilities each tier of lvls 6/11/16. I understand if this was possible and balance changes would have to be drastically changed to adjust power lvls of champions currently. I want power back to the players who wield the skill and knowledge to show off what they know on the champions they have spent the most time on. This I'm sure can be applied to other roles on the same exact issue. I want all roles to have a 100% to carry their own solo que not certain stages of them game to be relevant.

This post is open to constructive criticism and is strictly my own formulated opinion and just want to share my thoughts and feelings on being a ranked solo player.
