It isn't you. It's the format of the site.
When I started out my win ratio was just as bad. Now I have +130 wins.
You're a powerful debater.
I'll help you up your win percentage if you would like to have a few debates with me on more fun/silly topics, such as who is the best Thundercat? (Snarf, of course) Challenge me, if you dare! :) But don't leave!
Of course, this depends on how strongly you feel about your falling win-ration, or how much you really want a "fair debate". If you really are concerned about the above, then why not create a new account? You've been on this website for more than 1/2 a year, so you're rather accustomed, and thus a new account can be your chance to start from scratch, which may be a good thing, given that you already have some experience.
