After both reading this thread and thinking about my own needs, I came up with a heavy PowerAuras usage setup:
- Purple ring is Boneshield, it turns whiter as charges expire.
- Redish swords below is Blade Barrier, not as useful now, but made sure I spent my blood runes when I started tanking.
- Snowflake is IBF
- Yellow sign shows up when I either don't have HoW or SoE and I'm in combat.
- Green swords on top are for Cinderglacier/Fallen Crusader procs (PvP/DPS mainly)
- Teal shield on top is for avoidance trinkets/Lichborne.
Diseases and Unholy Blight are handled with NeedToKnow just below my runes, this is to have best possible disease uptime while making use of the SS glyph. Unholy Blight bugs a lot with NTK though and I don't really know why, many times the bar just dissapears when I refresh it which is weird.
I know ag_uf rune display is pretty terrible, but I haven't found a rune addon I like and have growned used to it. The thing that irks me, although I'm not sure if this is addon related, is that sometimes blood runes display as if they are death, but they are actually blood, and it messes up my rotation for a couple seconds until I realize it.
