Instructions
Run LazyBot.
Open "Combat System" from the menu on the left and scroll the toolbar down to match the class and build of your character. For example, if you want to automate a Warlock who specializes in the Affliction class tree, select "Affliction Lock."
Open "Combat Settings" from the menu on the left by clicking on it.
Record the sequence of actions for your class combat script in the list that appears. For example, an Arms Warrior starts with Charge, then Rend.
Change the order of actions in your action bar to correspond with the order of actions in the script. In the Arms Warrior example, move Charge to the first action bar slot and Rend to the second action bar slot. Ensure that every action on the attack script is placed in the same sequence in the action bar.
