Re: Critical review
I'd say practice last hitting a bit more. Though you had the highest creep kills (192), you could gotten a lot more, especially since the Drow in your lane wasn't denying.
Team work is hard to foster with a bunch of random strangers. It was dumb for your team mates to want to place you anywhere Slardar or Rhasta was without some back up. Blue was okay, Teal was an alright Treant Protector, but Spectre and Spirit Breaker... I think Spectre wasn't all that hot. Diffusal would have been a much better item to go for versus Desolator. Spirit Breaker, did he leave or lag out? It's hard to tell from replays.
It's hard to judge a player's ability without context. Considering the line up you faced from Scourge(Rhasta, Slardar, SA, PotM, Drow), I think you did ok. Drow was constantly ganked, thus messing up her mid-late game. Rhasta's recent Serpent Ward nerfed really showed here, but he was still a disabler to be recokened with. Slardar was pretty decent, and he kept Amplify Damage on you every chance he got. SA... meh. I did lol at his back dooring attempt at the end though. PotM was forgettable.
So, to sum up, more last hits, don't be afraid to deny.
