Core has been in use since HoT, constantly evolving to meet more and more needs, expansion changes, environment requirements and my sheer lazyness and desire to have to press fewer and fewer buttons.
Core is a scale-able boxing solution for 1 to ... however many characters you want to run.
Complete command system with extensive customization for every class.
Separate modes for mass farming, hunting, collections, gathering.
Extensive zone control for mob identifications.
Support for advanced looting.
Several modes of pulling.
