I have to say, I'm quite liking the feel of the build right now. Got up to level 5 today and it's just plowing through stuff. It's so much easier to hit stuff going THF it's ridiculous. Last life felt like I just couldn't hit anything at that level. I remember it took me like 30min to solo elite Swiped Signet on my previous life (ranger) and I just did it in 10 minutes on this build.
Hopefully it will be efficient at higher levels too.
