New Zed play style?

You can skip to 6:00 if you want to hit on what I'm discussing.

While many think the AS nerf on Zed was a pointless hit, could it be that this is the beginning of a means of retuning Zed to be much more ability reliant as opposed to dealing a lot of AA damage?

Could Riot increase the cool down on his Q and E early while decreasing their later cool downs and reducing his energy return on minions while increasing his energy return on champions to better slide him into a more ability based assassin and away from being able to act as a melee carry as a secondary?
