Would it be possible to give Aatrox a little more base health/defense?

I know he has really good sustain due to the built-life steal (and the boost when he is low health), but it feels like that part doesn't even really matter when almost every other Champion is able to hurt him for far more than he can them, with one of their AAs out damaging your lifesteal by a significant amount (not to mention said lifesteal is already only on the third strike.)

Compared to most other Fighters he just feels incredibly squishy, at least in the early/mid game when everyone doesn't have their builds starting up.

I realize there might be a bit of an issue with buffing him in this direction (since tanky-ness plus lifesteal could potentially make him nigh un-killable), but it just feels like he needs some more durability to keep up with the type of people he is primarily fighting against.
