Lack of ADC diversity?

Has anyone else been noticing this? I can only speak for my elo (currently Plat 2), but I really only see the same two ADCs in probably 90% of my games, those being Ezreal and Cait, with the occasional Jhin. I've experimented with banning Cait and Ezreal just to see what happens, and most of the time if I ban one of them, Jhin will be the next default choice. I mean Ez and Cait are essentially feeling like the Lucian from earlier this season. Are these two really that much above their counterparts right now? Seemed like only a few weeks ago I was seeing a fair amount of Jinx and a few Ashe's and MFs.

These champs do have quite a bit in common. Basically poke champs that AFK farm forever and are pretty safe, so maybe it's just a reflection of the meta and not these champs being super strong necessarily. I dunno, I guess I don't really care, just getting bored of laning against the same champs over and over again.
