I was deciding on buying several 6300 ip champions but then i managed to narrow the list down to two champions. Draven and Nautilus... I am looking for a champion that is well suited for solo ranked que and is pretty "op" in games when they get fed. Please help me choose one of these champs and give a short description :D
Draven is probably the strongest early game ADC; the "catch" is that you have to consistently catch his Q axes and trade with your opponent instead of backing off. It takes practice to do that, and he falls off late game so if you failed early game you're done. In the end, he's a good pick if you're willing to get good with him.
Nautilus can't cross walls, so as a jungler, you have to rely on denying their ward vision before coming in for ganks and only ganking pushed lanes (laning phase), and landing your hook when they use their escapes. He's like Leona but a jungler; your team has to follow up your engages.
I vote Draven, but they fill 2 or 3 different roles.
Wth does "Decesions" mean?
Anyways, most champions are "op" when they get fed but between Nautilus and Draven, I'd say Draven does more damage when fed. Nautilus has a ton of CC though and when he gets super tanky he is a real pain in team-fights. Personally I'd go with Nautilus because he is more fun, but if you are looking for raw damage then Draven is the way to go. Draven is kind of locked into the ADC role, but Nautilus can Top and Jungle, I have even used him successfully Mid lane against Akali, Zed, and Ahri.
Why Draven or Nautilus?
You can get much better champs if you have enough IP.
When getting fed, Draven will come out on top. The more you catch his axes, the more gold you stack. Kill an opponent and that gold is yours.
LMFAO You want a champ that is "OP when fed" and you say 
in the same sentence?
I'm not going to tell you which champ it is because you know damn well which one it is.
Okay, so here's the basic information on both when fed:
: He excels at locking down a target, and with the long duration on his shield, so long as the enemy carries aren't fed all to hell, you can soak a large amount of damage with the shield itself. His ability to guarantee a knockup on a specific target is also fight-breaking. He won't do any special kind of damage, on the other hand. He really just doesn't have damage skills, but he makes up for that with a stupid amount of cc.
: Draven puts out damage. Draven puts out a stupid amount of damage. Draven puts out damage so quickly and so stupidly high that he can oneshot squishies if sufficiently ahead, and I know of no adc save a Quinn with the drop on him that could actually duel him, purely because of his ridiculous damage. He doesn't fall off lategame, and in fact scales into lategame better than most adcs. What falls off lategame is his utility: he has a slow/knock-side, and that's it. He doesn't even have a passive after hitting full-build, because extra gold does nothing if you don't buy anything with it. That's why people think he falls off: passive becomes useless. Despite having no passive, he still does very well late game.
Tradeoffs of each champion
: He has a weak early clear and his ganks are far from guaranteed. Nautilus excels in situations where he can countergank, entering a situation with the ability to peel someone off his team with an easily hit anchor. However, if you miss the anchor, that's a lot of his "free kill" pressure gone, because he has no gap closers. If you want to gank as Nautilus, it's best to wait for the enemy to burn any sort of dodge ability first, then anchor. This usually means just walking into lane behind them and getting up close to snare with his passive.
: Draven is so mechanically difficult to play that a bad Draven is totally ignored after dying once. Nobody has to care about him because he isn't a threat. All of Draven's power comes from his Spinning Axes, and if he drops those, then he loses a massive chunk of his strength as an ADC. In teamfights, the mark that shows where the axes land makes it easy to toss cc where Draven HAS to be, forcing him to either take cc (which is terrible, as an adc) or lose damage (which is terrible, for Draven.) He needs a high level of mechanical skill to function against a decent team, but he'll steamroll anyone that can't deal with him.
