Tristana is super busted ....

But it does take a bit to reach said range. Her passive requires exp, and with the removal of catch up exp, she (relatively speaking) isnt as dominant as she was before now that comebacks are harder for her

Honestly, only thing i would change about tristana is her W: make sure it is canceled instead of still going off when she is stunned.

You realize that Caitlyn, varus(unless it was changed, don't remember fully), and Ashe have longer range than her, right? The issue is closing the game out early on so she doesn't get to that super long range. Caitlyn is amazing at this job, and is why she's historically been a counter to trist.
