I think you need to step away from ranked and do a little more digging into the game. I don't mean this in a rude way, but your knowledge of the game is little, and it's a bit flawed. Going into ranked, the general rule of thumb is to be able to play at least 2 of every "role" being top, mid, ad carry, support, and jungle. You should main something, but if you're last pick you need to fill in where it's needed. The next thing you need to do is get the mentality of "it's everyone else's fault" out of your mind. I used to have this all the time too, and it landed me at 800's for ELO in season 1. Now I take the time to think about the previous game and realize what I could have done better. A great practice is to watch your replays and see what your could have done better. http://www.leaguereplays.com/ <--- Download that and it will auto record your replays.
Again, I'm not trying to be rude, I'm just saying that I've been there and I think that you could have a much better time if you did those couple of things, and always remember, it's just a game
thanks for the advice, i'm really trying to follow it. i just realized i have quite a few mid champs that i never use anymore, so i was testing out Lux in an intermediate bot game.
i know, i made a few mistakes in that game, like not getting as many assists as i would've liked and a few other things, and i know you say i shouldn't always put the blame on others, but that loss can't have been my fault. well, laning was great considering i killed swain once (almost twice) and never died until the team fights started. i should've probably come to help top/bot more in lane phase, but when most of my team ends up with 13-14 deaths, i don't think there's much different i could've done that would've won that game.
i'll keep trying to get better at mid, then maybe adc and the other roles later on. i've never jungled before...
edit: i don't know if i ever want to continue ranked (maybe season 3???) but i do know i want to branch out more, so yeah.
