iv done the math

I know may people have a number of opinions on the new changes to the assassins but can I take a moment to say that they nerfed zed for no real reason. I mean he out of most of the assassins had the most health game play before the rework and now they have made his laneing harder with no real benefit late game then he already had. so first of all his Q has lower scaling not that bad as a change by itself but his W that this is where I think riot messed up his W while giving him more energy 10 more no longer gives him bonus ad I'll come back to this later the E had a damage decrease tell rank 3 and cooldown increase tell 5 so the ult now grants 5+5%/10%/15% bonus ad of the total ad of champion kill with the ult not when the ult is on them but with the ult itself and that comes back to the W changes no more bounes ad off of your own ad and the reason this Is a he nurf is because they made him worse at his early game but they also made his late game worse if you killed the adc at full build you would get at best 59 bones ad with the W now you get 78 ad so the thing I ask is why would riot nerf the only assassin that was for the most part balanced. thanks for the rant
