The biggest problem with low Elo is that you can barely climb by playing 'smart'
Going ham is the only way you can climb out of low Elo. Farming like crazy, playing super-aggressive, snowballing your lane, and getting ahead is literally the only way you can consistently climb.
Playing 'smart' alone has a very little effect on your Elo increase. By this I mean:
- Staying out of range from Blitzcrank late game.
- Not getting hit by the other team's AoE engage.
- Being grouped when you need to be.
- Not getting caught.
- Leaving caught teammates for dead.
- Disengaging from bad fights.
- Staying positive.
Things I listed above are the some of the visible differences between a Plat and a Bronze, yet a Plat who exhibits the above but doesn't snowball out of control often will climb very, very slowly, if at all. And it's a pretty big problem when smarter players are stuck with the players who feed, throw, get caught, and flame half the time, but can snowball out of control the other half of the time.
The traits you need to exhibit to stay at a higher Elo don't allow you to climb out of lower Elo.
You have to win the game by force.
Whether that means being farmed and putting out DPS, or stunning a whole team in a fight, or stomping your lane and being both tanky and bursty, or split pushing hard, or so on.
Last season I climbed into Gold with Volibear. Super aggressive early and engage fights late quickly brought me up a whole 11 divisions to Gold 4. But when I'm not playing Volibear, I feel pretty powerless, because even half-decent play means nothing when you can't forcefully win the game.

IS THE ANSWER
with my friend and are quite effective. I would say that yes playing smart is very possible in low elo. After one lane gets beaten by the other and the jungeler can no longer provide support we group mid. From there were do the little dance around and poke until somebody makes a mistake or we see an opportunity for a hard engage. Sometimes the fights are a bit sloppy because i dont know exactly when the
will ult or when the
will flash in but we just immediately follow up afterwards, and do our best to win the fight. To remind you guys this is with three randoms. To win one must do their best in lane, respond to their team, and when the fight starts to not back down. Even if I or another teammate screws up and im down to 300 health as
