What a lot of people don't realize is that the meta of the game shifts entirely around what skill level is being handled in which tier.
Posts have been made from diamond and platinum players saying their smurf in Bronze is very hard to get going because it's so different than the meta they're used to playing.
Team compositions matter in higher elo. At lower elo people have no idea what do to with them.
Bronze elo has been splitpush elo for a long time. A big frustration some players have is they're expecting that their team is going to instantly follow up on their engages, and they play something like Malphite top and get 5 man ults all the time. The issue is that, without a team following up on fantastic engages, you'll just die, you'll get frustrated, you'll tilt, and then the other team will snowball off of your good plays.
In Bronze, a champion that is self sustaining piloted by a map aware player, taking TP and warding flanks will get out of bronze no problem because most teams don't know how to handle a splitpush properly. If your team decides to engage 4v5, you can join with TP and you'll be okay (unless you're already behind, then something went wrong early). If your team doesn't do anything, chances are the other team doesn't know how to cross map, nor do they understand that you have proper warding and so they just give up map pressure when they come to chase you.
If you take that kind of playstyle and you stick it into Diamond elo, you're going to need a lot more set up because teams will actually know how to collapse properly, they'll know how to cross map and force the summoner spell advantage, and they'll know how to lose lane gracefully so you don't end up on a 7/1/12 Irelia,
Instead of playing more games, take the time to understand what the meta of your elo is. If you know your team isn't going to follow up on your engage.... don't engage. Do something else.
If you know your team doesn't know how to crossmap objectives.... don't put them in a position where they'll need to cross map objectives.
TL;DR. Don't bang your head against a brick wall. Walk around the wall.
