Which hero is best for 1v9?

It's not something you should try to do, since fighting is much easier to win with than farming, and having a "I must farm all the time" mentality is really not healthy.

But if you want some heroes that can carry bad allies on their own, here's the full list:

• My accomplishments

As you may notice, it's empty. That's because this is a team game, and being the one guy ahead of the enemies in farm doesn't mean a lot if the enemies lead all you allies in net worth, you're still playing 1 against 5 in a game that has halberds, abyssals, silver edges, and other things that'll make solo freefarm dota very hard.

Here are some candidates for possibly afk farming yourself to victory:
Anti-Mage, Sven, Juggernaut: These dudes can farm very quickly, and can potentially get a rampage with their ultimates if used well, and can offer a decent degree of splitpushing as well.

Medusa: You can farm fast, and in many drafts, it can become impossible to teamfight against you once you have that farm. She is much easier to counterpick than the 3 cleavers, and less mobile than them.

Arc Warden, Lycan, Lone Druid: These three can farm quickly, and rely entirely on splitpushing in order to win, manfighting and wiping them is not really an option, but killing their buildings super fast is the way to do it, and these 3 are unbelievable at it.

But you really cannot climb out when you are literally 1v9.

Blubbles, you've played with us before? granted atm i'm really busy exploring PoE and i can't kick it for some reason, but you've played with dotafire people before right? Every time we play, i really learn loads from the high 5k players, and even the 4k players like smuggs. I think that really contributed the most to me getting to my 3k mmr, and i even think i can get even more if i spent more time.(again, i'm addicted to PoE atm, someone help me pls, there's too many stuff to play T.T)

In 1k mmr, yes everyone is scrubs. BUT, that also means that if you've spent that long a time playing mmr, and you're still stuck at 1k mmr, maybe that means that you yourself need to improve. I'm sure you've heard that i calibrated at 13 too, at 1.2k mmr no less. i even dropped to 800 at one point. i don't like telling this story because it really sounds like bragging, but after not playing ranked for 3-4 months, i went back and steamrolled my way to the 3k breakpoint just before reborn. My Win-Loss ratio during that period of time was ridiculous, something like 7-8 out out 10 games won. that's the difference when you are better than your mmr, that's what should be happening.

Even if you are only a little better than your mmr, and win 6/10 games, you'll be slowly climbing, and you will reach your actual mmr sooner or later. The trick is to work on your gameplay, while you are playing. pick a small pool of heroes to play, preferably strong meta heroes. spectre 6.86 was a prime example, he was pretty strong by himself, and scales insanely well into the lategame. Work on how to best play them in every situation, and by the time you actually reach 3k, you'll be able to stand your ground.

Right now, i can bet if i look at one of your replays, i'll see you making tons of the same small mistakes over and over again, or not playing the most effective way. If you would just fix some of that, you'll get to 2k really easily, and maybe even 3k.

Oh, and don't play captain's mode in 1k, heck don't even touch captain's mode unless you are playing in a party. it's not worth the time.
