I think the new W and Passive buffs are good, especially since he gets the original passive increases earlier than before (At Levels 6 and 11 instead of 7 and 13), gets a another useful power spike at 6, and it scales better into the mid-and-late game in terms of damage output. As much as I hate to be the guy that brings up the Range issue, I'm starting wonder what justifies that Range now if he is being geared to scale better into the mid-and-late game because I only see the 40% Lightslinger shot at Level 6 helping his slightly-weak laning phase.
I understand making his Range shorter than 550 to make his hit-and-run gameplay more risky than before, but I always wondered when Riot began his update why his Range was brought down directly to 500 instead of trying out 525.

Edit - To add on to that, I went back and watched the 4.12 Patch Rundown to maybe see if I was missing something or if it was already explained. I think Snoopeh made a good point when they were discussing the Range nerf (Of course, his mobility and damage was relatively high at that time), saying that he could possibly have a hard time against many longer-ranged champions and Statikk says that it allowed them to "amp up the strengths of the character". After several of those were nerfed, it definitely shows in some lane match-ups.
It's good that they are bringing some power back to him now, but that brings me back to the earlier question of "Then, 500 Range made sense. Now, it doesn't. Why 500 and not 525?"
