Hey what was different from the current tree system, and the Vanilla Beta tree system?
Why did Blizzard originally change it back then?
what made Blizzard return to that old model which they scrapped?
Edit: I am talking about Vanilla WoW Alpha/Beta when Talent Trees locked players into a single tree, like the current system works in CAT.
Why was that system scrapped? And Why is Blizzard bringing it back?
