I'm guessing that set up is meant for very experienced players, you'd have to be comfortable with every hero to know that you can do well there.
I don't think it's the line up that usually loses games, at least in my experience, it's carries that can't farm. That's the main reason why I don't play carries, it's still hard for me to get decent farm and support don't need that many items/farm.
Also, last night game with Chrome and Dusk and his friend almost all of us were support... well, support/carry for some but still. The line up wasn't bad, but I think it's how you guys played that won us the game.
EDIT: I hate how people abuse bot games to win. They know bots won't do much so they can spend all day jungling... 50 minutes jungling to get all their items. If I just wanted an easy win I'd go easy bot games. I'm trying to learn how some easy carry heroes work and how hard it is to farm/get kills on some of them and that attitude just doesn't help. I like Drow Ranger and Sniper so far, they're easy to farm with and to get kills. I can't get used to melee heroes, they get harrased so easily, especially with plantain teammates.
