So i usually win my lane, i do objectives, team decides to throw example, they go farm top alone 35 minutes in while we are ahead, get ****ed enemy team gets baron and just kill everyone, so my question is, is there a champ that can take on 5 champs on so i can just carry myself ?

P.S if you look at my score some of them are good, some are bad it really depends if i just ran in and killed myself while joining the throwing party.

Singed I guess

1v5 is a thing of the past

Nobody can win 1v5, really.
Garen, Wukong and Jarvan, Darius (not recommended, low mobility) have some of the best chances, and oddly enough AP Teemo with a proper shroom kite.

Testing

well, if they are all standing there ready to fight, and u dive into 5 as 1, its basically impossible. but what u CAN do is take a bruiser and build dps and then catch people 1 at a time and basically one shot kids before the team can react, and pick off 1 or 2 and then your team can easily win a 5v4 or 5v3, but to do that u really need wards so either u have to further invest in a ruby sightstone or have a decent support on your team.

but honestly your best bet at a "1v5" is take lux and build mejals, and hit your ult on the whole team and let your team mop them up from 25% life. or just go suicide karthas and flash wall into there team and deal massive dps before u die hit your r and let your team mop them up from 25% life...i guess u can do the same thing as any aoe AP carry.

Singed can beat any team dumb enough to chase him.

Not possible.

1v5 is all I've been doing since I started playing the game... and my stats are the worst out of all the players out there.

I'm still trying though
