While I appreciate the effort you've made to improve Shadowdancer I do not think you are going about it the right way.
Firstly, you are adding way too much power again, and secondly you are concentrating almost all of it in one part of the tree. That will pretty much guarantee a set specification for people using that ED that is leagues ahead of others. Is this a desirable outcome?
What I think you should do (apart from fixing bugs and making the left side less clunky to use) is look at how you can adjust the cores to support more build diversity and reduce cooldowns for some of the active abilities many of which are quite weak relative to how often they can be used.
This just seems like more pigeon-holing and unnecessary power creep to me. It also suggests a lack of understanding of just how effective melee rogues are right now and what makes them that way.
Thanks.
