I'm currently debating with myself on whether its best to use text plus a cooldown bar (if the latter is needed for a spell) or use an icon with an animation (the first is usually done on weakauras, the latter on tellmewhen). I get a sense I prefer a text line with a color and a cooldown bar (the bar only if the ability is too important) because an icon is more 'abstract', and I'm not a toddler requiring shapes to recognize patterns. What do you think, what's the best approach to display aura/info on the screen with such addons?
PS. Don't tell me circular auras that encompass the whole screen a la how blizzard does it now too. I hate those. They are too big and only cover one spell usually.
