So is Tristana ADC or an Assasin?

So 2 major attributes assassins have are:

Burst to kill a single target Mobility to dive in and then escape with safety

So in a nutshell, an assassin if it carefully picks its target, should be able to burst it and then escape without dying otherwise playing assassins would be considered suicide. Now tell me, where in the world does Trist not have these 2 attributes? Let me also clarify that her jumps are actually much larger than your normal ekko,vayne dashes, more like akali and diana dashes which are actually their ults. Then if we were to talk about vayne who apparently has more stealth and burst than shaco, it is no wonder that these 2 adc's are currently dominating the meta. League of One Shot.
