Elo and Kill Death Ratio

So how do you tell if someone is good just by looking at their dota stats?  Sometimes elo (for those who don't know what elo is) is the best identifier and other times its the kill death ratio (KDR). Here are some of my thoughts on how to interpret some of the different stats you might see.

Every new name created in pub leagues starts at 1000 elo. If you win games your elo goes up and vice versa if you lose. So a high elo is generally good. It usually means the player have more wins than losses and means they help win games more than they help lose games. But when you see a high elo, you also have to look at their games played. A 1200 elo with 500 games played most likely means the player is stuck at that rating. 1200 with only 30 or 40 games played means they shot up from 1000 pretty fast and are probably better than what a 1200 elo might indicate. This follows a pretty standard rule of statistics: the bigger the sample size (games played) the more accurate the data is going to be (elo rating). So when you see a player with plenty of games played, the average of their stats should be a pretty accurate estimation of how good they are.

The big problems in trying to pinpoint someones skill level by stats is when they don't have many games played. This is where someones kill/death/assist stats come in. In dota, if you get a kill for every time you die, you'll have a 1.0 kdr. Usually anything below a 1.0 kdr isn't good, but that doesn't account for someones assists. If someone played a support correctly and had a high amount of assists to deaths, their kdr would be low, but they still might be damn good.

Heres an example of a random game in dotacash:
As you can see all of the players except two have enough games played for a good estimate of their skill level. But how would you rate the player living-on-video just by his stats? Well you can see he has won both of his 2 games and has a 9.5 kdr. Also being up 32 elo in 2 games means he won ~16 each game which indicates the teams he was on and played against had around the same average elo. So this player living-on-video helped win 2 games and had a great kdr, I would guess hes a much better player than troll-dad, who only has 1011 elo with 56 games played.

Getting a good estimate and your teams abilities before you play with them is always a good thing to do. A low level player might do things like auto attack, push the lane, fail at harassing, take unnecessary creep damage and etc. If you can expect how your team, as well as the enemy, might play, you will reduce the chance of being surprised by good or bad play from either side.

Next, I will cover a few aspects of laning. And if you have any questions about this post or something you want me to talk about next time, let me know.

New Design

So I decided to make my blog all fancy lookin. I tried to keep it easy on the eyes for reading still while adding a bit to the style. And yes I know, the Lina/Morph background is pretty legit.

Lemme know what you guys think.

The Pregame Game

So you've logged onto WC3 and are going to play some dota. I bet most of you actually enjoy winning more than losing, so there are some things to consider before you actually start playing the game. I'd say the first thing is the league you play in. I personally play on DotaCash since I feel its the most active. I don't feel like waiting forever for games to start and they have a nice interface online to get the game names copied.

My first advice is pick a league to play on and use their channel or site to find games. If you are picking the first dota game you see from the list of custom games WC3 generates, then you are hurting your self. If you pick a league to play in and join games from the bots in channels or from the site, you will end up playing with more people who stick to that league. This just means you will have people who have some degree of care for their stats or the league they play in and have a less likely hood to leave. Think about it. A person who picks random games from the custom game list wont care about stats or bans and that just leads to lack of care of game play and possible leaving/feeding. So the first thing is make sure you stick to a league. It might even make you care more and be less lazy in game.

Next time I'll try and go in depth with analyzing players stats.

Welcome to Pub Dota Talk!

Hello everyone, I'm here to talk about pub dota. But first, what do I consider pub dota? I think the leagues that make private and public games and have a variety of players ranging in skill levels - from terrible to semi pro. Leagues like DotaCash, DotaPub and THR are some pub leagues.

I've only been playing dota for a couple of years now, and I feel that the average player has nothing to really follow that revolves around their skill level. So here I am. I'm here to talk about all the things that I see in the skill levels that populate pub leagues.

So where to start? There is so many complexities in dota. And even when you may have a good grasp on the game, theres more. I guess what I'm planning on doing is writing little discussions and guides for what happens in pub dota play. These blogs most likely wont be valid for what happens in some high level scrims or pro play, but I'm sure they will help for anyone interested in getting better in pub games with random people.
