General info about my TellMeWhen setup across all toons
The main goal of these TellMeWhen icons is to be aware of the most important information while being able to focus on the gameplay and action. So you're not staring at action bars so much, as it's bad for your health in raids, dungeons and PVP!
How to import:
Just copy the text-string you can find at the bottom of each post, ingame, open TellMeWhen with /tmw and in the window at the bottom there's a text-box, paste the string there and on the right-hand side choose import from string.
You'll import my entire setup, but don't worry it's easy to remove, edit and add other stuff to it.
The general setup is this:
There is always a Left, Center and Right ability icon. These show the most important DPS abilities for your class so you can make well timed decisions, using only one or two icons was too limited. Usually this consists of DOTs to apply, Heavy Hitters and other rotational abilities.
Sometimes Meta-Icons are used that contain more than one ability in the same spot (A Meta-Icon links several Icons in an order).
DPS and Defensive Cooldowns (based on a health %) and some Utility abilities are given a separate icon usually to the left or right of the Center Icon.
Some filler abilities without a cooldown don't have an icon if that's the ability you use when no icons are showing for that spec. For example: Frostbolt, Arcane Blast, Devastate, Lightning Bolt (Ele), etc.
Abilities that have short cooldowns are tracked though, for example Bloodthirst, Crusader Strike so you hit them each time they're available.
To the left and right of my action bars are two icons each that track stuff like DOTs, Debuffs and Buffs. Sometimes there are smaller ones above them that track more of the same, this was necessary for specs like Brewmaster and Windwalker Monk which have a bit more to track.
Over my Chatwindow is usually a wrong/missing Stance/Shield/Aura/etc icon. You'll only see it if you need to take action, once you do, the icon is gone again.
Here's a 6.0 Paladin video to show it in action:
