Did you read the guide or what?

too squishy and rushing infinity costs way too much without giving you as much damage as a cheaper bloodthirster would be worth. infinity jsut sin't a great item on riven. and those boots are the second worst in the game next to enhanced for out of battle for 5 seconds, either go cd boots or evne better merc treads

Then please vote up! :3

im loving these builds

pro

Yeah I find riven to be tanky enough with just 2 dorans but a frozen mallet would be very good earlier on.

i like a lot.. but in regular 5v5 wouldnt you get frozen mallet a bit earlier, for mid game durability, and i am going to try few of these builds, sheen raven? never tried.. looks like a must, but overall.. Nice guide, i love riven, you did good.
