Just a heads up for everyone. While there is a /follow command and /assist and /aid command (1st targets your target's hostile target, 2nd targets your target's defensive target) that's about the full range of useful macro options at this point.

There is no ability to globally accept quests, there is no /cast, /castsequence, /use, conditional button press or targeting modifiers or any of the other rich macroing tools that WoW spoiled us with. Fortunately or (un) there are also far fewer skills than in WoW so you don't need nearly as many key options.

BTW, the devs do say that the system underlaying their UI is on or better than a WoW level for flexibility, but I have yet to see any APIs to give some ideas about addons. I suspect that it may be THEORETICALLY more flexible than WoW, but I highly doubt that EAMythic will allow a lot of the really interesting mods that really expand WoW's functionality.
