really just play what youre best at tho, i got out of bronze easily once i decided to main adc and stick with it
Really, anything that scales really well into late game without having a stuff early game will do well. That's why I would say to avoid Vayne and Twitch for now, because you'll be useless if you get stuff on early game, but most ADCs are fine for that purpose. The reason I suggested Riven and Gragas was that they are incredibly strong at all stages of the game, and both champs will serve you well all the way through Gold if you ever have to play top or jungle, respectively. It can be any champ as long as they snowball out of control though. I'll go a little more in depth why I believe Riven to be the best at her respective role in Bronze.
Riven: Riven is an absolute beast. Ridiculous level 1 all in with Q-auto-Q-auto-Q-auto ignite, will kill most, if not all top laners at level 1, especially in bronze where they don't respect Riven's level 1-3. If you start long sword 3 pots and rush Brutalizer, your lane opponent will cry because that cloth armor they're going to have to buy is basically going to do nothing for them anymore, and CDR is the most broken on Riven of all champs in the game, because it grants you both stupid dmg and mobility. If your opponent is a pansy and stacks armor, build last whisper after brutalizer. If not, get that Ravenous Hydra as fast as you can. Build the CDR boots and then finish Youmuu's Ghostblade. Youmuu's Riven is better than Black Cleaver Riven IMO because people underestimate the value of the active and the 15% crit chance it offers. Nobody expects to lose a trade because they got crit by a riven. 15% is the sweet spot of crit chance for you. After that, build Last Whisper or Ravenous Hydra, whichever one you didn't build first, and then you have a decision; go a Maw of Malmortious or a Randuins Omen. Hold up, Cappy! WTF are you doing? Why are you building defensive items on Riven? Because you already have more than enough damage to blow up anyone, even their armor stacking tank, and it gives you more survivability. Top your build off with a Guardian Angel and you're good to go, even if they focus you in a team fight, you'll be tough as forget to kill, and they have to kill you twice! For skill order, I go Q, E, W, and then max them in that same order. You can max W before E if you want, but I find the added mobility and bigger shield from E to be more useful in dominating your lane. For combos, you E in, W, R, Q-auto-Q-auto-Q-auto, then R again if they haven't already died to you. Enjoy going legendary.
Pros to playing Riven:
Ridiculous early game
Scales super well
Does tons of damage even to tanks
Battle Bunny Riven
Cons to playing Riven:
Your team will rage at you for not picking a tank
Dodge vs Kayle, you will not win a farm lane or a kill lane vs her. Just Dodge, she's your hidden worst counter
Silences will make you cry
