Unlike Yasuo, Riven is not a omnipotent being. Though possessing considerable amount of damage output and very impressive maneuverability compared to other generals, Riven can still be spotted by other attacking agents, especially ranged fighters. Understanding the road racetrack will be the premise for you to build the right fit for that battle.
The Meta in the Legendary Alliance is always changing, and in each version, there are always strong elements that outstrip the rest. For example, at the moment, it is Ornn with lots of damage and control skills, besides the high basic stats. Your task is not to try to force yourself to the same power (because you will often ... lose), but to find a way to go safely and ensure the amount of equipment to catch up with. Match time.
For example, some harsh hardships when encountering ranged generals are Jayce, Kennen and even ... Teemo. Jayce with extra damage will squeeze you while choking soldiers and call people to go on forest continuously to make you either abandoned the road, or lose the network. Kennen will not stop teasing you after every phase he jumps out of your combo with just a Thunder Speed. And Teemo with brand name Blame Blight and Guns ... then no need to describe more suppressed when confronted with this mini satan ...
well,good review :)
