    Credits: Manciuszz & eXtragoZ

    Changelog:
        > Updated priorityTable with new champion Aatrox, made Alistar, Nunu,Taric "Tank" priority.
        > Now works in games with below 5 players.
        > Target Selector mode switched from TARGET_LOW_HP_PRIORITY to TARGET_LESS_CAST_PRIORITY, because it is more reliable.
            > Reduced 20 lines of code.
