All I see is ezreal Lucian Graves and the occasional jhin

When I play adc I'm a diehard ashe player. From what I see ezreal and Lucian are the safest when it comes to escape with ezreal being a bully with little counterplay with a icebourn gauntlet. Personally I don't understand why kalista the Queen of all adcs is not played more. She has the adc main dream kit but I think that the current meta Is forcing champions with dashes. Everytime I play ashe I feel like my slows are useless because almost anyone can just dash to me. I know that this is the counterplay to ashe but when Udyr is faster than me while I'm slowing him down I'm concerned with movement speed and dashes and the state of the game. Normally ashe would be able to lock down Udyr but right now Udyr is just way too fast due to how easy movment speed is to get. Caitlin was top adc season 5 but least played season 6. The fame is going to change and I get that and I enjoy that but currently there are about 20 champions in the game that are just played wayyyyyyyyy too often. I know nothing can be done about it but I think if there were more keystone available it would open space for champions like singed who currently done not have a favorable keystone.
