It will be interesting to see how these change over the course of the season. But for those who do wish to see the highest levels of the game, these can help provide some insight into what other players are doing. Not all players choose to push high-tier content and that's fine. With aggressive gearing and deep class knowledge, you can probably make nearly anything 'work'. These are not meant to say that you cannot make any class or build viable or fun. These are meant to examine overall trends we're seeing on the top-tier Normal Seasonal leaderboards. The numbers presented are a snapshot taken on Friday, March 3rd, and will go out of date quickly. In all cases but one, the Haedrig's Gift set is falling to second place, and in one case (Necromancer), it's already fallen to third place. Although you can get the full Haedrig's Gift set within several hours of play, not one of these sets is leading their class in overall Leaderboards. Looking at the first week of Diablo III Season 28's leaderboards has been interesting, particularly watching how players are beginning to migrate away from the free Haedrig's Gift sets to those gearing strategies to ensure high-tier success.
