i climbed from bronze 4 to gold 4 in 1 month. i'm just wondering what i can do better, my best rolls are top/mid/adc but i can play everyone roll so in champion select i typically fill. i have a good champion pool for all rolls also and i ALWAYS pick champions to benefit the team. in-game regardless of my roll i ALWAYS ward and i make sure to always buy pink wards. i try to encourage my team to buy wards and also the team and guide them with pings. the problem is people NEVER listen. i never rage about it cause i know i can't make a difference by typing in caps lock. i had a easy time in ranked until this point where i am now. typically when i suggest something they reply with an immature comment. should i just not saying anything?! what's some tips that i could use to guide my team to victory and get me to platinum. if you have questions just comment them cause i really want to get better!

UPDATE: just got promoted to gold 3. thanks for the help!
