How was your day today? - DotA 2 Edition

http://dotabuff.com/matches/667869867 Why is it when Slark is on my team he's awful and loses us the game by not pulling his weight but when he's on the other team he slaughters us?

Same reason as when you play Axe and you get no spins compared to when you play against Axe that doesn't stop spinning ever, even if not attacked
They fixed that though, but Lich feels that way now. A friend's been playing it lately and he gets the worse bounces but when we play against it we get rekt.
