I started part one as an introduction, to set everything up. While "yaw" (keybinds and macros) and "pitch" (procs and cooldowns display) are important parts of a UI, you can't start doing your damage dealing job without a health bar to take down. So this week, we're going to look at all kinds of health bars you can find on a warlock's UI.
You can see all my unit frames in action here in the full version of the header image. Remember: I'm using the addons I use as examples, because it's easiest to draw from what I know. You can be an accomplished DPSer with minimal addons on a mostly default interface, if you so wish.
