Losing his shield destroyed his ability to take any sort of trade. He has no defensive steroid at all in the lane phase, and while his damage is a bit more decent now, you're better off playing an actual bruiser for better damage and some sort of sustain mechanic.
His passive means nothing because he's still forced into mana crystal first buy and you can't do anything else otherwise you'll just be OOM.
Ornn top is essentially auto loss more often than not, I can't speak for other lanes, but he cannot trade anymore.
Granted the changes did make him scale quite a bit better, it won't matter because the game is almost always over by then anyways and someone is running someone's nexus down.
