General Discussionhelp me improving my gameplay

1.Your team was total trash and no one was there to tank or initiate.You couldnt win 5v5 fights there maybe take racks counter push but not easy
2.Team trash.Why no bkb ? why orchid ? Hex is ok but not sure was needed as 2nd item there maybe atos or shiva before hex would be better
3.You trash.Why aghanim sf ? i mean i never see miracle anyone go aghanim unless they have 15 -0 at 10 min u have alot better items ...even cyclon isnt needed ..just play manfight sf
