this is the reason people lose 100% of the time
because you rely on other people. you gotta do things yourself.
people always bitch about support not warding. tf?! im pretty sure you can buy wards at the store. i mean fuck, rito gives you one for free. . ever seen an lcs game? EVERYONE buys wards, not just support.
mid lane didn't call mia? how about you're more aware and ward more? obviously if someone leave the map they're only doing 1 of two things. Recalling, or ganking.
focus on what YOU CAN CONTROL, not on your "shit jungler" or your "noob mid".
dont focus on things out of your control, like enemy jgler camping, bot feeding, etc etc. focus what options you have in order to help out your team mates.
who can carry you if you play around him or your 1-10
top who you just need to engage and distract / buy time in a team fight for you to carry. I always make suggestions to my team (never tell someone exactly what to do imo) like "locket would be really good this game" or "we need an upgraded sweeper for Vayne." If someone is feeding or playing terribly the last thing you want to do is remind them about it with a unnecessary comment. The best thing to do is to just keep playing and say nothing. Your team will notice when you are focused and in it to win it. For example, last game my team was bickering about the enemy fed Ryze. As they were re spawning I was doing scuddle. "drag 30 we can get it" I said and dropped a pink ward in river, as an ADC. After that the focus of my team was changed from what went wrong early game to what should we do next.
