I don't know if this build is the *best* or completely and fully optimised, but since I've been running with it I've been having a lot of fun and no longer feeling like I'm the weakest person in the room. I'm not quite to the point where I'm able to do the same things that some of the uber people I run with can do, but I can hold my own easily, and it's been going very, very nicely.
I'm not used to having a medical power that can help others, and Vengeance is one of those that's very conditional since things have had to go very, very south before you can use it. But I've liked it.
Just my two cents and feedback on it. Thanks for posting it!
