I have played a lot of champs that can top or jungle like Shaco, Olaf, Warwick, Wukong, Zed, Lee Sin and singed. I don't like Nasus and Mordekaiser. So I'm looking for another top or jungle carry. I was thinking Riven or Hecrium but I don't know, got any ideas on what champ to play? I'm not talking about just Riven and Hecrium.. Any champ, who you think is good even the champs I listed, that was just to show you my play style.

Hecarim can carry games if you don't fail at ganking, he's the kind of bruiser/tank/initiator hybrid that can wreck the whole team apart if you have at least half brained teammates.

Noc is also pretty good with the new itemization and jungle. His ult is godly mid-game. Riven is okay, but she won't have the best ganks and she needs to be squishy in order to deal damage. But a fed Riven can solo an entire team.

I like the horse but don't wanna rely on the team

well, he's one of my favorite junglers and I pick him even though team is in derp mode. He fits the bruiser role perfectly. Build him tanky and with some damage items (TF, Black Cleaver) and you'll be both hard to kill and able to deal some pretty good damage.

S3 has been very kind to Nautilus. I just jungled him for the first time since reworks and found that he can absolutely melt people if you build him bruiser. With red buff, Spirit of the Lizard Elder, Ignite, Sunfire Cape, and his W you put down so much DoT pain it's ridiculous. Not sure how well building a Lizard Elder would work for top Naut, but Naut has been my favorite top since his release.

Hmm I mean do you still carry with Hecrium with people who aren't as good as others?

Lets see:

Darius most definitely
Jax same as Darius+cheaper
Elise maybe (not to sure of her jungle in s3 but it seems fine)
GP
Fiora (the new Tiamat is really strong)
Pantheon if you have the balls
Kayle (unsure of jungle in s3, can pretty much go in any role)

Riven and Hec have different play styles I actually don't get it, I initially thought you were thinking of champs that can solo top or jungle and have the potential to carry a game. a well built hec is impossible to kill but isn't likely to get kills unless you have all the space in the universe to stick to people and chip at there health. Likewise Riven can definitely take some people down and has decent mobility (is mobility the play style your talking about?) but her jungle wasn't exactly great to begin with probably along the same lines as Kayle jungle. All three of which I'm unsure of now in s3
