That's a shame, because the depth level and variety of the genre is absolutely amazing once you get to know it. 1) Read a few guides and play against bots to learn the basics stress-free offline. Whenever you can beat the bots, you're ready to go online. 2) Do not play All Pick if you solo queue. 3) Be a nice dude throughout the game, and ask other nice people from your team to play again. Add them to your friends list, and after not long you'll have 1-3 guys to queue with most games, which helps a lot.
I just don't think it's for me. It's why I love Minecraft so much, sure there can be a lot of action where I could be working in a team but other times I could just be standing there talking in chat. I haven't been on there in ages, but there was this server I went to practice my German and most of my time was spent just talking in chat or me listening to them speak in Teamspeak. I just don't see that happening in Dota 2...
