I think the point of this thread has completely escaped people. This is not about demonology warlocks, this is about ALL warlocks. The point of this was to talk about a talent that is simply not attractive or effective for many people and whether it could/should be improved to make it a more viable choice for all specs, rather than just one.
How many people who are NOT demonology use or will ever use Service?
Are we supposed to know who that is? Why should we even care who you are, lol? And what makes you think you speak for every person who plays a warlock?
