Sort into:

    - heroes
    - quests
    - horde allies
    - alliance allies
    - neutral abilities
    - class-specific abilities (INCLUDE class-specific pets/allies in each stack)

After this, to sort alphabetically, a quatering distribution is to:

    #1: A-D
    #2: E-K
    #3: L-R
    #4: S-Z

        (just memorise "AELS")
