Blizzard has posted development notes on today's Warlock changes, noting that the goal of reining in the Demonic Core economy is to reduce mobility.
You will see several talents removed as well as new talents being added. We’ve also reduced the number of available ranks across the talent tree.Cooldown Alignment
We are removing all talents that reduce the cooldown of Demonology’s summon abilities and baking in those decreases baseline so that they align in a way that makes sense.
These talents, along with the varying cooldowns, made playing Demonology more convoluted and difficult, especially for new players. This should free up some talent points and require less problem solving when it comes to trying to ensure your cooldowns align.Demonic Tyrant
We are moving Summon Demonic Tyrant to the center of the Demonology tree to make it much easier to access.
When we first set out to design the new talent trees, there was an idea that we could make Summon Demonic Tyrant an option against abilities such as Nether Portal. However, Summon Demonic Tyrant is so woven into the identity of Demonology and synergizes so well with other options on the tree – it’s difficult to have anything else compete.Doom and Vilefiend
We are expanding upon Doom and Vilefiend by offering new talents to customize and upgrade these abilities.
We want to ensure that these are competitive options with one another in both single- and multi-target situations so please provide feedback if one or the other isn’t quite hitting the mark. In terms of Immutable Hatred and the “Felguard portion” of the tree, we want to retain that as the passive damage opt-in for players who prefer that kind of damage profile.Demonic Cores
Our goal with reining in the Demonic Core economy is to bring Demonology closer to Affliction and Destruction in terms.
