User blog comment:TheHellDoIPutHere/Supports and You/@comment-5589202-20130719162750

I find bad supports a lot more than good supports. That's why I play support a lot and I am good at it. I prefer supports that can heal and be aggresive at the same time, like Sona. I try to build mana, mana regen and cdr as soon as possible. That gives decent sustain to the entire team, even with the recent heal nerfs

I think supports by themselves are rarely the main reason why a team loses. Mostly it is because lack of cooperation or lack of skill in some teammates
