Blizzard released a new blue post explaining more clarifications on the announced Diabolist Warlock talent tree in The War Within.
The main concern this post addresses is the way the Diabolic Ritual talent works.
Players have expressed concerns on how Diabolic Ritual would work between Demonology and Destruction, as the entire talent tree is based on Soul Shard consumption, and as of right now in Dragonflight, Demonology generates and spend shards a lot faster than Destruction, making Diabolic Ritual seem that much more powerful for Demonology players.
