I'm at work, sometimes I have to tab out when a coworker wanders by. Just saying it's annoying to reply to a post, only to find that post deleted so nobody even knows what I'm on about. I could see leaving the conversation, but why delete the post?
Was in main DPS rotations at the level cap. Will be pruned like all mechanics that have become outdated. You're not making much of a point here.
These were accounted for before healing was added to the classes in question. The game has been through many iterations of balance where warlocks had self-healing and rogues/hunters/etc did not. When these classes suddenly gained self-healing, warlock self-healing was actually nerfed to an all-time low. Warlocks did not receive additional mitigation. Other pure DPS did not lose mitigation. So why the sudden shift? No reason really, Blizz wanted to help out those classes in the leveling process so they shoehorned healing abilities into classes that were never meant to have any. Then when these new self-healers actually had a number to compare to warlocks, they used that as a reason to QQ until warlock self-healing was nerfed closer to their level. The messed up part is that the numbers people cried over were largely from out of combat and pet heals, leaving warlocks a mere shadow of their past self-healing strength that made the class unique and attractive (and function solo).
Meh, you're just gonna be obtuse now so I'll leave you to it. People with valid points don't delete their posts.
