you're playing nidalee, that's not cool
Anyway, I agree with everything DD said, and I also have an idea of my own.
I had a look at your S3 stats:
You kicked ass with Irelia last season, but this year you haven't touched her with a ten foot pole.
Might be wingin' it here, but perhaps you should give Irelia a try. You had a lot of success playing her last season, so wynaut give her another shot? Just might be the key to carrying yourself out.
Other than that I haven't any other ideas.
P.S. Sanguine Blade is an awful item on ARAM.
EDIT: If you're interested in trying out what's strong right now, I looked at some numbers and saw that this champ is absolutely crushing NA Silver:
While I don't encourage picking champs simply by their current strength, if this champ is your cup o' tea, then might be worth trying out.
