well the witch belts are mostly for high levels anyways so of corse high level dudes are gonna camp there xD
besides that, i camped in king sage cat all day and managed to keep 17 of all the chanels, u just have to remember it spawns every 45 minutes~
i got about 350 tokens just on that day :P
but if ur not that high a lev, boss monsters in pqs drop them too so you still have a chance
