Honestly not a fan of preseason thus far.
I always used to say that the worst thing for any league player was for their main/favorite champion to get buffed to be OP and become perma-pick/ban until they get nerfed. I was wrong. The worst is when your favorite role gets buffed with a cool rework that makes everyone else want to play it.
I never used to have issues getting ADC. 4th or 5th pick? No problem, still got ADC 80% of the time easily. To the point that I actively picked others roles (e.g. mid) when I was a really early pick if no one indicated they wanted it because I got to play my preferred role so much.
Now even when I'm 2nd/3rd pick I can't get my preferred role :( When I'm first pick I feel guilty about taking it because always at least 1 person asks for it (and I always used to give it up when someone asked for it because I got to play it so often). At least I'm not playing ranked yet this season - hopefully things will settle down in a couple weeks...
You missed AP assassins too - they're also strong because they're often the best at quickly taking out an ADC.
