Why i hate AD mains

A trend I have noticed in a few profiles is that the ad carry role is the game decider. so why is it that the team with the higher win % ad carry always wins?
Adc mains complain all day about how weak their role is and how mages are taking over bot lane. But, all riot did was give you guys more to play than the same 3 crit champs 6 seasons in a row. NA has very popular adc main twitch streamers such as Tyler1 and Imaqtpie. All will state opinions on how their role is too weak. They don't play any other role so they aren't very good at League of Legends, their knowledge is limited so when they make braindead comments the hoard of plat 4 adc mains in their twitch salute them.

Let me give you my straight opinion on AD. The role is so good that it allows these hard to punish marksmen run wild. The reason is because supports just do so much damage early on into the game that when bot lanes play safe a jungler cant do anything, and they scale. that's why there is often 4 man dives bot because you need 1 more man to shut down the oppositions ad. If your ad can safely farm and let the other roles do their thing every game will be decided through jungle difference or exposure of skill. Korea likes farming so much because they've realized how good it feels to fight properly with items.

If an ad took any logic into consideration, a ranger can deal out tons of damage to an army before they even come within speaking distance. but when the knight suited for close combat meets the guy suited for distance there should never be a case where the long distance guy wins. But adc complain when they die to champs like garen because they aren't good enough to kite.

Think competitive. The goal of each fight is to let adc kill front line then kill other ad. the reason is because of how much damage output these champions have. A fed top lane only means side control, a fed mid means river and lane control, a fed jg means jungle control and a fed support means roam control. but a fed ad means a free carry as long as they are alive, force every role to play around them so the game can be won.

League of Legends is a genius game, there is a lot of thinking into everything. Riots game is fixed Tyler, its just that Riot cant fix their player base. They've given us sandbox, bots, normal, custom, ranked, flex, aram, treeline. ALL of these modes can improve something wrong with you. But instead of fixing that problem complaining is the best option.

Riot is giving the Crit champions new items to work with, but I promise it wont be enough to satisfy these treacherous players.

Maybe im salty because the new ranked system is putting too mismatched of games, or that na is doomed because of main character mentality. either way im fed up with how ranks state is right now.
