We saw watt the riot rwork did to kassadin, but wat exactly has riot achieved with the Trist rework?

They strengthened her adc aspects so all her skills were actually useful. In the process, they made it so AP Tristana has to actually autoattack 4 times for her burst instead of spamming all her buttons then W'ing out again. It turns out people mostly played AP Tristana for the easy point and click nukes and don't play her now that she requires actually being in range of the enemy for a significant amount of time.

they also made here the fastest demolition expert in the game.
