League of "blame everyone else"

I am in the silver elo (bouncing between S3-S5). I cannot stand this elo, not because I am some elite player but because people at this level seem to be completely delusional. I main jg and I can't count the number of times a lane will push the enemy to their tower only to be ganked/killed over and over. Who do they blame? The JG naturally, any wards? of course not. I recognize the importance of counter ganks but I have to consider the possibility of a 2v2 and a likely loss. I played support morg last night and the mid ahri lost her lane miserably and tried to roam bot and failed. Who does she blame for the loss? The support who "doesn't know how to engage"... Sorry what? I fully admit I have a lot of things I need to work on (hence my elo) but it seems this is a rare trait in the silver elo hah. Last few games I played reasonably well and lost http://na.op.gg/summoner/userName=Poenacanuck . The only champ I have a decent winrate on is Nasus... lol. If anyone has any tips I am all ears, constructive criticism is welcomed.

Thanks!
