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.
