I know it would be a pain in the butt to do if you use multiple classes on a regular basis, but if your anything like me and you HATE the tool tips when hovering over skills with your mouse on your hotkey bar, I have a pretty easy solution.
Just Macro your skill and place it on your hotkey bar instead of the skill located in your 'Abilities and Traits' menu.
An example for Cure.
Code:
/macroicon "Cure"
/ac "Cure" <t>
/ac "Cure" <me>
As you can see some macros will take some extra commands to make them work as they would if they where from the 'Abilites and Traits' menu.
