We lost ad carry?

I played league of legends for 8 years. It has become an important part of my growth. I have gained a lot of happiness in it, whether it is playing with friends or e-sports competition. Over the years, I've played every position. Of course, my favorite position is ad carry. Or, it is now called bot line. Once upon a time, ad carry could take the game by its based attack in summoner’s rift. That’s what ad carry means. In recent seasons, I am easily killed by the top, middle, jug and even support. Some would say that you can't blame the rules for your poor performance. So see the esports, How long has it been since we've seen a regular marksman in the world. Some would say kai'sa could carry the game，xayah could carry the game, sometimes Ezreal could. That's true, but the only criterion for whether anyone finds it in control of the game is whether it has the means to protect itself. When there two marksman champions left in World Championship, should we be aware of the version of the problem. As I pinned my hopes on the upcoming 10th season, I found that my EXP with the two-man side in the bot line had been cut back. Well, I am now 2-3 levels below the other lines average in mid-game, so they can kill me much more easily. What can I say? There is a joke, Roit removed the marksman’s ability to occasionally take control of the game. For some reason, Roit wants to shorten the average time of games. The marksman, who has lost a lot from that, deserves to be compensated rather than re-injured.
