Cool, you nerfed her movement speed and ult speed. how about nerfing something that matters, idk how about the fucking shield that turns her into a bigger tank than udyr? nerfing her movement speed doesn't do anything... at all... she doesn't even walk anywhere... she just Q's. when she can literally 1v5 with only a hydra then you know there is something wrong.... so please for the love of god nerf something that matters.
LoL Wiki, click Riven portrait and learn what she can do.
Ask friend who plays Riven and invite him to a game and practice against her.
Easy tips.
oh look, the OP is silver IV
well how about you actually get good at the game and then get back to us about whether riven should be nerfed or not
or just get good?
or pick somebody that does well against Riven? 
You are exaggerating waaaaay too much. First of all, she can't "1v5 the entire team with a hydra" second, her move speed does matter. It cuts her mobility so that she CAN'T q everywhere whenever she wants. And by the wat, her Q is an 8 second cd at level 1. She can't "Just q anywhere" anyway. Her shield is fine and just because she has one doesn't mean she's "tankier than an udyr" she's a lategame bursty champion and to counter her, you need cc
They will never nerf anything that matters on Riven because she's a poorly designed champ that would become fucking terrible if they did. Like even if you removed the hidden power of animation canceling on her Q, which lets her dump one of the highest fighter level burst in assassin time, she'd become so much worse (I'd like to see that change anyway, but it'll never happen)
