Why does Riot hate ADC's so much?

I'm really struggling to figure out why ADC's have so many disadvantages compared to other roles:

- Bad Armor/HP/Magic Resist, making it very easy to be one combo'd by any assassin. Doesn't really matter how well you do either.

- Completely reliant on making it to late game, which is happening less and less as seasons come and go and as matches get shorter

- Splits experience with Supports, so you are always down 1-3 levels early on compared to mid, top and jungle, making it harder. This is one of the worst things about being an ADC, because there is no way to control this aside from going solo.

- Slow and often have no escapes. Some of them do but this is pretty much an ADC trademark

- Heavily reliant on expensive items, while tanks can buy a lot less and do a lot more

- ADC items are pretty shitty in general. You are looking at a 3000+ gold item for just about every ADC and for me that's going to take 12-14 minutes. Losing Yomu's AS Active last year really hurt ADC's.

- Bad early game, which really hurts when games are short.

- Little more than a pinata for junglers to gank time and time again. ADC's are always the first target for ganks.

- Requires tons of good movement, spacing, last hitting and there's little room for error.

And when you put it all together, ADC is easily the hardest position. Not only do you have to deal with this, but then you have to deal with your support, who might be helpful and other times wants to take your farm and fight more than you do.

No other class has these kind of issues and I can't really say the late game tradeoff is really enough to make ADC worth it.
