i think there are 2 reasons where increasing is good; 1) Those hunting cards can exclude certain items which generally include (Arrows/Crossbow arrows/Card A/Card B/other etc's along the way) 2) Those daily bossers where their exclusion list include (Mesos/100nx/250nx/5000nx/various books/drops) Given those thoughts in mind, I would say increasing it to 10 seems sufficient as normally those doing 1) will tend to do quest specialist medal as well (in which increasing to 10 slots helps to alleviate the problems of picking up untradeable loots accidently) and 2) where they wouldn't have to constantly change those books/drops in their exclusion list. It would be a pretty good QoL imo
Suggested it in the past, and then i was told you can actually increase the ignore list by up to 3 times. All you gotta do is have 3 pets and 3 pet ignore! https://royals.ms/forum/threads/increase-pet-ignores-number-of-slots.139873/
