Okay let me get this straight about the Assassins rework...
Don;t get me wrong, Riot, you guys nailed the mobility part, but assassins are suppose to be "High Single target"?????? How is that even possible?
Main source of burst is her passive, but to trigger that you need to "pick up" a dagger. How are you suppose to pick out the carries when no smart player is going to stand next to a dagger, especially, the carries that have dashes and such? I mean the amount of time it takes for a dagger to land is enough for them to create some distance. Her ultimate does really high damage, but it isn't instant and would rarely if not never take out anyone from full health. Her q and e alone would never burst anyone. This one is more of a weird rant. Why does she have so many high AD ratios? Just seems like another case of 
Passive is also the issues. She does do a lot of damage, but that 1.5 delay thing makes it way to difficult to burst anyone fast enough. You have to stick with your target for a bit to burst them, but you are easily vulnerable getting cc'd or the carry just simply walking away during that small period of time. That delay is even more ridiculous in a team fight. Worst part is her passive is completely useless until level 2 or unless you take the chains at level 1 which I do just so that I at least have a passive until then.
