Think about it this way. gives a flat bonus while and  gives a better ratio. Assassins in particular have immense ratios and don't really require better ratios. They would much rather have a strong flat bonus since the flat bonus is just so massive.

ADCs on the other hand have mediocre ratios in comparison, this means they want to amplify their ratios by making the ratios on their autoattacks stronger. Crit can reach such a massive scale of damage and a good way to determine how much damage critical strike chance offers is by multiplying the critical strike chance by the. Pretty much every ADC will reach eventually. With a the estimated damage offered is:

.15% * =

Compare this with that costs  and gives only. In terms of only autoattacks, gives more damage than  and only costs. Of course there are many other factors that change this but ADCs generally have tools in their kit that trend towards autoattacking rather than spellcasting, that said will generally be more effective on them.

I have to disagree in terms of though. There are quite a few ADC that prioritize attack speed over crit chance and early on. This is typically due to very powerful on-hit effects they have that inevitably makes the DPS gained stronger than the or  gained. Taking as an example, if she has  at level 3 and a rank 1, with her default , she would have DPS of:

(3* + 20 true damage /3 attacks * 0.696822 attacks/second = 42.97069 total damage/second

With a, she would get 49.93891 total damage/second. But with a, she would get 49.05719 total damage/second.
