I'll be honest, I have a huge attitude problem, and I'm not entirely sure how to fix it.

Back in S4, I managed to finish Gold 5. Got my skin, was high on life. Season 5, I kept failing promos out of S1 and end-of season lost enough games straight to drop to S3.

Placements this year put me in S4 and I've been to S3 2-3 times, just got demoted after a 7 game losing streak. I do good in spurts, but then it just turns around. I don't know if its my champion pool, random luck, or what. I would like to think I try to work with my team, I do tons of TP ganks that usually turn out well, I try to run champs with huge tank or utility, this season my favorites have been Vi and Nautilus, but there's just something every game that goes wrong. Sometimes its off-meta picks that get absolutely wrecked, sometimes its a bot lane taht goes combined 0-8 by 10 mins. Or the ever-popular AFK/feeder/troll. I'd like to be able to be able to carry myself but it sometimes feels like my team always has a handicap. What is it exactly that I can do to make myself better to the point of climbing? I've been under a 50% win rate almost all season, the clost was 49% with like 2 games off of 50%, but then it just took a nose dive. If anybody has advice for me, I'd appreciate it.

Edit part 2: I am a Top/Jungle player, prefer playing Vi/Hecarim/Shyvana (Wish could toss ASol in there, but not good enough yet) in the jungle and Kayle/Nautilus/Darius/Garen top lane

Edit part 3: Gotta love when a Draven instantly starts trolling because you don't gank his lane the instant he asks you to
