Can't bring myself to play another champion

I love playing League, and over the course of 2 and a half seasons I put over 8,000 games onto Jayce. I enjoy playing Jayce a lot, but I feel like i'd have more fun playing a champion like Draven who can carry by stomping lane. Draven in general is a lot of fun and I feel like could allow me to actually carry games. With Jayce I feel like theres way better options out there, so I just feel irrelevant all game long. Laning phase I cant seem to get a kill because by the time I use all my mana for harassing, the enemy just gets healed back up from Corruption Poition, Resolve, or Dorans Shield. Just feels like im useless. While Draven had always been a relevant ADC in the bot lane.

The problem is, Draven is a completly different champion compared to Jayce. It feels like all the time i've invested into Jayce would be completely useless if I decide to drop him and pick up Draven, but it might be better for me in the long run. I'd have to learn how to not only master Draven, but to learn how to play ADC role in general. Where to ward, what to do, when to fight, where to position myself. Id have to do this all over again like I did with Jayce, and I just cant bring myself to invest another 1k games in a different champion just for a possible chance of being better with them than Jayce.

Anyone else having this problem?
