I wouldn't think LFR is all that hard to add. Most fights are pretty simple and have a few phases that are each pretty simple. People only have a hard time becuse to a human, its data overload so they dont see a debuff or dont see they are in the fire etc.
To a bot its as easy as knowing what debuffs go on someone, what to do and executing that. For the most part the execution is one of two things 1. movement somewhere and/or 2. a spell cast.
98% of the function and work is already there they just need a script.
