Lyless, it sounds like you created this post to just attack anyone who posts. Venting or not, if you're looking for constructive feedback, I will speak on that.
Solo Queuing is more challenging now than previously. When it's a group queue you play against and they are well coordinated, it sucks, i feel you. Like someone else posted before me, if you belong in a higher tier, you will still get there. This season, what i've noticed, it takes much more tenacity and near perfect game play from you, if you want to climb. Win your lane and start helping the other lanes, obtain the objectives, etc.
In low silver, i noticed you have to take charge more often and redirect your team to objectives. I'm not sure what rank you are, but understanding the fundamentals of the game and knowing what your team needs to hit next to win helps your gameplay and leadership tremendously. The reason I mention this is because I became frustrated many times when we had leads, but my teammates would start roaming the jungle, trying to hunt and chase enemies. In low elo gameplay, its extremely toxic and everyone wants to prove to the other one that they are better. That's not going to win you the game.
Also, another thing i did when i would lose and become frustrated, I would check out my match history and see what was the problem. Sometimes i would notice that i would pick carry roles and I wasn't doing that great, compared to the enemy carries. What i did was i would play support for some games, kind of chill for a bit, and do my best to support my teammates. That's when your leadership skills need to kick in. In teamfights, you aren't the first to get focused, so you are more aware of your surroundings than say your adc who's trying to run away from talon. Make Plays, Lead the team, and make it your goal to die less. In the end, all you can say is you tried.
