Picked up a new build type on Riven that works super well, but can suck hard if you lose your lane early. Steam rolls really hard though.
Red elixir / 1 ward / 4 pot -> Brutalizer -> Bloodthirster -> Last Whisper -> Maw -> Hydra -> Bloodthirster -> Black Cleaver
Shield is massive, and the damage is phenomenal. Super super squish but can make insane plays.
started going strictly 9pots 2 wards on riven, my win ratio jumped up incredibly well.
have been going x/0/x as well.
dominate my lane, am able to get a BF sword or better in my first buy everytime now.
before i was going long sword + 2 pots >.> now i realize how bad that is. lol. My core build for her is BT->Brutalizer -> boots -> BC the rest changes depending on the matchup (as well as what boots)
