During the presentation, Blizzard announced that it would fix some bugs in Season 2. Due to this, some of the strongest builds will be weakened.
It's no secret that some, if not most, of the strongest builds in Season 2 were due to bugs in the game. The developers didn't fix them, which would have resulted in fewer interesting characters.
But the launch of season three next week will change all that. As stated during the broadcast, the gaps will be corrected, and the list for “liquidation” included a sorceress with the skill “Ball Lightning” – a clear favorite in popularity in the second season.
There are the popular “Will of Thibaut” pants, which in the case of some versions of the rogue means that the player can accumulate not the standard 3 combo points, but even 23, which affects the damage. These and other builds will weaken, and in general Blizzard admits that the “Supremacy” mechanic is currently too strong and will be “softened”.
The developers note that strong characters are, “cool” and enjoyable for players, so finding the right balance is necessary. This may partly explain why errors discovered at the beginning of the second season are only now being corrected.
