I don't have a lot of friends to play dota with, so I get randomly matched to people I don't know. Sometime I win, other times I lose, I guess that is how it suppose to work. Some time I got matched to someone that is really good (at least for my MMR), I'll send them a friend request and literally do whatever it takes if they can help me win. This one time I had to wait for the guy for 30 min. And that got me thinking: instead of wasting $$ on cosmetics, why can't I pay these guys to play with them???
