-Exaggeration, her shield does not have 100% uptime. Try again.
-You don't have to blow shit on the shield, it lasts 1.5 seconds. Wait till it's down, which isn't long (Half the time you're stunned during that time). Try again.
-Animation cancelling is not a hack and isn't bannable. It's purposefully kept by Riot, and most champs can do it. Riven just has more use for it. Try again.
-She is not invincible, Zhonya's and bard's ult makes you invincible. She is killable easily, even if you don't wait for the shield. Try again.
-Riven can be kited, she can be slowed, stunned, snared, etc. Sure she's not as kitable as Udyr or Darius, but she is kitable. Try again.
-She can be CC'd by anyone, unless covered by a Morgana Black Shield. Try again.
-Riven does not get tankier than an ulting Mundo by pressing E. All it does is give her an effective like 400 health for 1.5 seconds. Muno's ult restores most of his health, and usually all of it, which is far more than 400, especially with SV. Try again.
-Riven's W is not a targetted AOE stun. It's a melee, close range aoe stun, self cast. Try again.
-Riven's ult does not do 100% max health true damage. Just gives her some AD, increases attack range, and can be a physical damage AOE execute, but only working on low health targets. Try again.
-Her Q does not move her twice as much as Kass's ult in one charge. More like the other way around. Kass's ult makes it farther in one cast than two charges of Riven's Q. Try again.
-This quote captures her personality in her owner after she was betrayed. Try again.
No one is fighting you with downvotes. You're just taking them as you deserve. Try again.
