With thousands of games of experience in high plat/low diamond, I've played each of these champs from both ends enough to get enough of a base knowledge for how the matchups can and should play out if played correctly. While they won't go as planned 100% of the time, the matchups section is made to give anyone who is brand new a good idea of what they should be considering.

Thank you! :D I'll keep dedicating time to make it even better!

A lot of high elo people give out generalized answers about things, but if you really crack people open, they can talk for hours on this kind of stuff. I try to write down everything that goes through my head before entering these kinds of games on Tristana to help people who aren't confident in what they should be doing on her.

I'm glad you like what I've done so far :D

Absolute Focus has been considered a much better option since the changes to celerity a few patches back. Essentially, Riot wanted celerity to be more beneficial specifically to champions that utilize some kind of movement speed increase (ex: hecarim, rammus, etc.) Absolute focus guarantees a lot more damage on ADC's in general, but can you can take Celerity in some specific cases. Sometimes on champions like Twitch I'll take Celerity and Nimbus Cloak, giving extra movespeed and damage along with it. This can be specifically good when you need to kite quickly in teamfights and pack more of a punch in the crucial moments. But yeah, in summary, running Absolute Focus and Gathering Storm on Tristana, is the best choice ~95% of the time.

If you run into heavy AP lanes, then you can feel free to replace Absolute Focus with Nullifying Orb.

Also, you can opt for celerity if you have movement amplifying teammates (ex: Zilean, Kled). That's probably the only time it would be better for Tristana.

Thank you! Will do!
