Ming, I'm really curious what you think the major defaults of the going with Assasin over Combat are? I mean sure imp sprint, AR,  and mace stuns are nice but is it really worth all the things you lose in Assasin tree?  There just seems like so much that is nice about assasin.  More damage, tons more combo points, CB, crit, murder, run speed etc. I would really like to see you spend some more time testing a build simular to this on test 21/0/40 is what i'm using live but on test I would move some points out of SC to FF and CR. The burst on this build is so nice. And you are always a bit faster than everyone else like a rogue should be. Hate to waste a sprint when someone is just 1 foot out of range.

I believe that AR/prep is going to be best for 5's however I'm considering going more like 25/0/35 for 2's and 3's. 

I'm curious what you think and would love to see you put some time into testing that build
