Why I ban Zed in every game now

If only you could grab him / cc him in time ... ahem
Just had a game where I was 
and my ADC was 
doing really well. She was 7 / 3 / 0 and I was 1 / 1 / 8 at the time. We were stealing their jungle's red buff. She was at full health after, and as we were going back- suddenly a 
appeared with 
activated. I immediately tried to stop him, but he did his shadow leap before doing R on my ADC.
Once he appeared, me and her managed to kill him (he was 5 / 3 / 4 at the time) and the Zed ult was pulsing. Despite being at half health, she used 
while I added both 
and 
onto her. Nope, she died ... my stacked items and her summoner spell wasn't enough to keep her alive despite she wasn't almost dead. I'm sorry, but that's a bit ... much in my opinion. Before you say "Just build a 
then!" most ADCs don't build this because their life steal / dmg usually makes up for needing a second of invincibility.
So yeah, i'm going to ban him every game now because he can leap through any cc, press R to be invincible, and possibly escape while your ADC / squishy is going to die regardless of the stacked heals / shields. If it's bad now, i'm worried about how horrible the Assassin's Rework is going to be like.
(armor buff)
(armor buff and ult which also reduces damage taken by 50%)
(20% on ult)
(Q lowers zeds AD) etc etc
