i maybe wrong but if you encounter and have a choice doesn't it have limited time to choose? I mean after some time waiting it will skip itself?
ok, u get enc with wolves, u deny, but u dont have mantis in ignore list, then u get encounter with mantis and wolves... mehh... its just too complicated, and so not needed, u just can one click to cancel enc.
Maybe if if we had an entire list of all the variable encounters and encounter mix types....Maybe your right.
