How fizz and zed should be
I saw in some other post that someone said Khazix is a really great example of what an assassin should be, compared to fizz and zed who can dive and take no damage . The point of an assassin it to be able to completely dominate a 1v1 but have more trouble if others show up, unless their fed (fed=great assassin who can destroy multiple people)
The nerfs to fizz next patch don't accurately make him into an assassin, they really need to change is e so that he can still apply damage and be untargetable for a short amount of time. His E giving him a second like flash is what makes him less of an assassin.
For Zed he has way to much mobility with his shawdows, I get that's his lore thing but being able to trade with w and his ult makes him feel way less like an assassin. If they made W so you couldn't trade with yourself I think he would like an assassin.
