Yesterday on the LotRO forums, Narrel, Turbine's Games Systems Engineer, posted a clarifying note about why the company chose to implement this and where it plans to go with it. The devs' main priority with Lua scripting was to empower players to tweak and modify the user interface more to their liking, as the default UI cannot be all things for all folks.
While it is going to prohibit mods from botting or macros, Turbine will open the field for players to work with the inventory layout, information that the HUD displays, quickslot bars, target info, fellowship info and raid vitals. "We are very excited about this feature," Narrel said, "and look forward to the day when it goes live allowing players to have a much more customizable experience with our graphical interface."
