These are all the Premium guides (Premium guides are guides that are so good that they deserve an special place in the forum. This guides a pretty much perfect and explain the hero in high detail. They are selected by mods). If you need any other hero guide, ask for it and I'll gladly find the best one for that hero. Here are some other Premium guides that are miscelaneous.
