So I am the classic feeding bronze 3 riven mainish. I want to climb with riven but in bronze they just play faceroll champs and beat me, should I climb to like silver with some bs annie or yi and then learn riven in a higher rank. And before you say drop riven, I actually know that you dont just take TL, that you build accordingly, im working on combos but its not working out very well, should I keep practicing until the season ends and hope for the best during placements?
Hey! I love riven too! ^-^ If you're going to rely on Riven to carry you out of bronze, GJ, keep that mentality. Though, is your skill and mental mindset there? Practice does make perfect so you're also right. Bronze is kind of hard to get out of being that the majority of league players are in that rank and are also trying to get out. Less than a month until the season ends, so I say, getting into a duo with a silver and get out!! Remember, you have to understand (if you pick riven) " Is this champ going to help my team comp? Is this champ going to help me win my lane or should I pick something else." For me, I'm thankful just to get into Gold this season haha.
Anyways, best of luck. [slayer-pantheon-thumbs]
if your not climbing tbh it has nothing to do with the champion you are playing it just your own skill just try to isolate where you need to improve your gameplay in general and work on that the champion doesn't really matter.
If you follow these tips it'll help greatly (coming from a stubborn former bronzie yasuo)
If you love Riven, keep playing her.
Research ALL of Riven's match ups good and bad. Read any commentary you can find from Reddit etc, and watch streams of the laning phase for Riven. The idea is to read about the match up and combos (theory) then see how it was applied.
Once you pick up a new combo/ trick etc that you aren't too good at, take it to the bot games and give yourself similar/same match up to practice. The beauty of this is after 5-10 min in the game you can reset and practice from early game again. Practice taking the roam too.
Finally I suggest expanding your champion pool with at least two other champions that can flex pick. I suggest that they each have different playstyles and at least one of them be AP based in dmg.
Quinn and Cho for example or Rumble and Wukong Practice applies the same to them, but they are mechanically less demanding than Riven. The point is back ups
The rest is macro game my friend
Did my team pick no AP? - MIght want to go AP, and play like you expect a camp. Did my team pick no Tanks? - Might not want Riven as you'll be adding to the squish Did my team pick range or not enough? - If your pick has most of the initiation power your positioning will matter more

Hope this helps
I'm glad it does man. Pretty much anyone who plays 
or 
knows that there is a mental war you gotta get used to. These champs destroy and gain all the props when you're winning, but when they lose its like opening a salt mine. You'll win, and you'll lose, so its best to not add everyone that adds you after a dope match or to listen to the salt mine workers when you lose hard.
That being said, if I were in your shoes I'd spend the next few days doing like 3 bot game runs, 1 or 2 normals, then test in rank. (take breaks) If you win the rank, maybe play one more rank if you lose, maybe practice against who you lost in a bot, run another norm, or put it down for the day.
The high tilt factor in Bronze can be mind numbing to just throw yourself against. And when you hit a good stride you might come across that smurf who reks you so bad you doubt your progress at all lol
So stay positive, really think about the specific points where you gained/lost advantage. I wouldn't give up rank for the season, I'd just spread out your games. Play ARAM for fun too. You could care less about winning or losing those and they give you team fight practice
If you can't climb, invite some friends to play with you, if you can't climb with riven when its something to do with your skill.
