You should post a build for feedback. That's how we can all improve. I sure as hell learnt a ton like this .
What was cool though was that my very first post was a build guide meant to help newbies like myself even though I thought I was pro back then. Nowadays I'm and experienced player but I'm glad that post aged very well with so many views and I'm glad I helped many people .
