New Zed's dying, give old Zed back!

Just played some normal ranked in the morning, as all the lane except mid were taken (support was taken by a duo bot guy), i picked the most mid i played which is . Also wanted to mention about which is "broken" as he just needs to sparm Q early and get some kill then get fed by "stealing" with hi's E and escape with his ult. Back to my topic, in the lanning phase i destroyed , by then later, in teamfights, i feels useless as thier support is a which hard peels thier carry, everytime i goes in try to assassinate thier carry, i found myself a hard position which my damage is'nt enough (because thier CCs) and can't back immediatly as new needs to wait 1 sec before he can use hi's ult again. When thier or other ones is'snt together with thier carry. Thier carry won't even try to fight me, he/she turns and run into thier team (I didn't dare to go chase because i would have a long distance between my team, not worth to change with thier carry as my team isn't fed enough to fight 4 vs 4). Then we ends up defeating in the baron pit.
