I think, after playing dota for around 50 hours (of human vs bot matches) now, I just had the first game where I think I did "decently".
Played as sven. Laned with a Razor. Early game was me AoE stunning the two bots and then us pouncing on them and killing them. Eventually got stronger and actually managed to buy a lot of items from the build (treads, bkb, leech helm etc.) Also kept dying to a minimum.
I must say this is getting more fun and fun by the game.
Still quite a few games away from human vs human matches though...
