How exactly is the indefinate CoC kiting supposed to work, anyway? Whenever I tried it, I'd either miss monsters 'cause they were out of range, or I'd get hit when I moved in to CoC again. I had the extra range talent.
It takes practice, and having a general idea what size a monster's hitbox is.
DEFINITELY make sure you don't have Frostbite, a single mob getting out of the pack will fuck your entire wagon, and fast.
