Low-manning some of the older content helps too, also find a friend that is an experienced whm and have them show you the ropes or pay attention to what they do during aby events or other events. Big thing to remember is try not to pull hate, so don't spam the biggest cure you have, and rememer reraise. I personally also have had great success using macros with the syntax of <stal> so you can easily scroll through the pt list and not have to deal with the pt members blinking all the time.

Keep at it and you'll do great
