Macros
Been over this several times but this wouldn’t be complete without stressing the importance of macros once again. Your brain and the time restrictions on casting, lag, recasting and healing back MP and avoiding agro are the ONLY things that should come into play. If you are loosing ANY time at all maneuvering thru the interface to execute an action odds are you need better macros. I’m not going into specifics because by now that should be a dead horse if you have read any of the other guides myself and others have written on the subject.

Managing rest time
At low levels resting during combat is not much of a concern but as you go up in levels it becomes the difference between a good party and a bad party, if not a dead party. In a sticky situation the time it takes to stand from a resting position and begin casting can seem like an eternity. By the time you stand it may be too late to save the person you were going to heal. Standing around waiting for someone to get damaged enough to warrant a heal when you could have been resting means potentially not having enough MP to finish the fight or needing too much time to rest between fights preventing exp chains. Balancing these two extremes takes a lot of practice. Regardless of the reality of group synergy if you don’t do this job, up to the standards of your group, you will be blamed for any and all failures. Learn to shrug this off or learn to be perfect.
