Two Issues with the Assassin Update

I like what riots doing with the assassins. There's just two main issues I have.

1. Akali Shroud Change

When mentioning akali, you guys said you wanted her to have a more dynamic fighting style. With the way you guys made her shroud, It feels like you made it more linear instead. I use my shroud to farm cs because almost everyone beats her pre six and can just harass under tower. But now, since the duration was lessened and I cant place it where I want, It feels like I have less overall mobility and control. The blink is nice and is a good way to give a champion the ability to outplay opponents, but because her shroud is placed at her original location, it doesn't have that much use. To fix this, it would make more sense to put the shroud at the location she blinks to instead of behind her.

2. Lack of AP/Magic Pen Items

With the amount of ap assassins in the game, it feels kind of unfair that they don't get any new items or updates. One glaring problem i've always had is that there is only three magic pen items in the game. And even with all these items, you can't kill an adc who only has a maw. Compared to the amount of armor pen, flat and scaling, it almost seems ridiculous to only have one actual magic pen item. There are a couple of ways to fix this. I think that lich bane, being mostly built on ap assassins, should give a small amount of magic pen. I also think that there should be a similar item to black cleaver, but maybe without the health. Champions like diana, akali, ekko, kat, or most of the ap assassins could use a stacking mechanic to whittle down MR.

It is VERY important to note that these items should be tailored to AP ASSASSINS. Mages getting too much mr would make them extremely strong, more so than they already are. I say this because assassins are supposed to take out priority targets, but mages getting too much magic pen can wipe entire teams like brand, vel'koz, annie, etc.

If these are taken into consideration, that would be great. Thanks for reading.
