Aatrox's Buffed Passive Adjust thought (riot employee respond if possible)

I've played a few games of Aatrox on pbe and one thing that I've had a problem with is timing the engage against ranged aggressive champions and passive/aggressive ranged champions and straight up aggressive burst melee. My passive either takes too long to proc and im nearly dead by the time i get the buff to fight back and revive with 400 hp to get 1 shot or I'm stuck in a limbo in lane due to the enemy backing off every time my stacks are high enough to engage or when they know i have ultimate leading to my passive falling off in 4 seconds then they go back. Playing aggressive just leaves me open and I'm too weak to handle the gank because you know, my passive takes too long to stack and it falls off when I cant even get near minions to stack it what so ever. I think this needs an adjust and would like to refrain from sending this to live without a proper fix.

Another thing is if you wanted to increase his window of attack and aggressive play why remove his one aggressive tactic of level 1-2 engage on enemies, not its impossible due to the passive stacks unless the enemy actually goes on you which you have a high chance of losing level 1 and somewhat of a chance of winning level 2 that's if they choose their moment incorrectly

possibly make the timer for his stack falloff increase to 6 -8 seconds? i see no reason for him to be stuck in a permanent limbo against people that know what they are doing

I like aspects of his kit but his passive may be an overstep. If it is possible I'd like to speak to a designer or someone with the idea behind his passive changes by removing aggressive strength for a pseudo aggressive power.
