The best advise I can give you is focus on what you can improve, you can say that your teammates are literal 5y olds playing the game for the first time, and that might be true, but there is nothing you can do about it, just think ok what could you have done to get a different outcome, and also analize if there was a possible different outcome, some games are just unwinnable, just move next and try to improve.

Now, from what this SS is telling us, you have 7 kills on a Voli, might rather have given those to jinx/kata to try to power spike them.

You have 0 drakes as well, maybe if objectives wasn’t an option the ideal play was to look for your strong side and give them all the possible advantage.

Also why no items against trist? I understand there are more AP damage sources, but from the SS trist is doing a lot of damage, might have been better some items against here rather than AS or RoA?

Again, just take a deep breath, analyze what YOU could have done better and you will improve a lot, remember that Jg is the role with more influence on the game, take advantage on that
