Tips for carrying in solo queue? (LAS)

I don't know if region has anything to do with what's happening to me, but here is my problem: I consider myself someone who isn't the best, but knows how to farm, when to engage and when not to fight. I'm not great, just awake enough to know those two things. But LAS probably is the most toxic community. You get flamed for everthing. Don't even try to suggest what objective to take. They are all pros. They know that after acing, it's recall. After pushing, is backing on spot. And that killing the 0/7 supp>inhib.

Anyways, one thing I can do and always works is to kill the enemy threat when my team gets caught. Because the enemy team does the same stuff and engages randomly. I use GP for this, building crit ensures me a 2shot kill on the enemy mid/adc, winning us the TF, and I can push while they back or go get the golems.

If this doesn't work, I die, my teammates want to avenge me and die, and we all lose.

Of course, I do get carried time to time, and good players also exist. It's just when stuff gets salty, everyone gets mad. But like, 100% of the time. There's no way to stop someone raging at you if you give FB or a double.

TLDR: Recommend someone who can jump into the enemy team, kill a fed adc and escape. I'm not good, I just want to get some tips on champions and ways to kill the enemy threat.

Thanks a lot and I hope you have fun in the league. Peace :D
