Literally the only change Tristana needs is for her W to be interrupted by any hard CC.
I have been complaining about this bitch and her w for literally years. It's not like Ezreal's E, which is also a blink and his only safety feature, and it acts just like Tristana W.
Tristana W doesn't require skill or timing to really do. You pretty much cast it before CC hits you and then literally nothing can stop you from jumping away.*
* except thresh but that doesn't count
Not only does she have massive range, she has best-in-class safety and nearly the best damage - the only person who scales harder is Kog and he barely performs better because he's a squishy egg that gets instantly crushed and Vayne has a weaker knockback (albeit tied to hard CC situationally) and only has better DPS if you consider her against tanks.
Also, why the fuck is her ult a goddamn aoe knockback. Yes, it can, situationally, knockback 2-3 people or maybe their entire team.
Fuck Tristana, fuck her W ignoring CC, fuck her resets, and fuck pretty much everything else about that champion.
hey I can cancel her jump
