How's the new Tristana?

Gameplay notes by Vesh from http://na.leagueoflegends.com/en/news/champions-skins/champion-update/champion-update-tristana

Old Trist was a late game powerhouse who didn’t really have clearly defined weaknesses. Her power dipped in the mid game, yeah, but when you look at other super powerful late game carries (think Vayne or Kog’Maw), she just didn’t have the same Achilles heel-type glowing red spots for her enemy team to pew pew at. She had insane range and speed with her basic attacks, and even when she did get caught, she had a decent knock back AND a lengthy jump that let her GTFO. Changes were needed, and after deliberating with the rest of the champion update designers, we decided to cement Tristana as a daredevil reset carry who gets bonuses from (rocket) jumping into fights while removing some of the safe strength she had in her kit.

Now, instead of operating as an uber safe right-clicker, new Tristana’s power is windowed, with huge power spikes when she’s played to meet specific goals. Her basic attack speed still increases per level, but the boost is lower than before. This makes Rapid Fire actually important, as she’s not just switching from stupid fast attack speed to soul-crushingly fast attack speed. Her Rocket Jump now deals lower base damage, but can deal way more if she stacks up Explosive Charge on her target before landing on their face.

So, how do you like Riot's new direction for Tristana? Do you think they achieved what they set out to do?

Personally I feel that the attack speed reduction was a bit severe. I think it would be better if her base attack speed was increased and the steroid on Q lowered instead. Furthermore, the range decrease came out of nowhere and I really don't think she deserved it. If her new E gave her too much of a good early game, then perhaps gate her passive so that she won't have too good of an early and mid game, but leave her late game alone?

I also tried building her AP, and it seems that an attack speed / on-hit variant is more effective now. Building Nashor's Tooth and Wit's End gives her the attack speed she needed to complete her combo faster. Hextech Gunblade seems like it'll be good on her too.

What are are her new best items? Statikk Shiv for the burst, especially since she got a reset dash or Phantom Dancer to make up for her lower attack speed? Is AP Tristana still viable? How do you build her?
