you can also make a macro to equip skills and equipment
heres an example of mine for a gladiator
/equip main "Weathered Gladius"
/eaction 2 "Light Stab" main
/eaction 3 "Phalanx" main
/eaction 4 "Circle Slash" main
/eaction 5 "Provoke" main
/eaction 6 "Rampart" main
/equip sub "Worm-eaten Square Shield"
basicly equip main means equip an item in your main hand, so equip sub means equip an item in your offhand
eaction means equip action (as in ability or skill) and the numbers 2,3,4,5,6, etc means equip the action in that slot so 2 would mean slot 2 on the first action bar and so on. Make sure you put the "" for the action to be equip this is important. Last but not least you need to specify which hand you want the action to be used, in my case I want it to be my main hand so i put in main, if your offhand to execute it then you would put sub.
