Hi, I appreciate your appreciation post. From all accounts the Devs who actually do the work on HOTS are allocated few resources and I know I was elated simply seeing a different splash screen after 6 months.
This is though quite unfair. Even if you take a cursory look at the forums you will see posters here who have created multiple hero guides, the The Hall of Builds is a good example of this.
Master players here have also coached people in game one on one one offered assistance here on the forums. Yes not all these topics are on the front page and you may have to look for them, but they are there.
