is bork rush still the best option for twitch?

not sure if anything's considered as "best option" for twitch anymore compared to the other adcs...

Probably if Twitch is still on the High end for base AS.

I think BotRK was a go to item for twitch prior to the marksman patch (4.10) That when BotRK went from a situation health shred and niche pick, to a more general ADC item. Now, BotRK most recent nerfed returned BotRK closer to what it was prior to that patch.

But If I was to play Twitch as the sneaky Assassin type, I would probably want BotRK for it's active. That will help you secure kills.
