I've been doing a lot of Big Fishing lately and the exclamation points are important for knowing what fish is biting, but these do not appear if you have "Show Limited" selected.
I personally don't like the crazy graphics happening with my character during content which is why I have "Show Limited" as my option. However if you want to do fishing you kind of need/should have the exclamation points turned on, which means I have to swap my settings every single time I transition from content to fishing.
I cannot imagine the fisher exclamation points would be considered in the same category of graphics as normal combat graphics considering how much more elaborate they are compared to just a simple pop-up of !, !!, and !!! for fishing.
I would also include mount animations as something else that should be included but I'll accept just the fisher exclamation points if needed.
Or better yet make separate categories for each thing, because "Battle Effects" does not exactly fit along the lines of Fisher or Mount animations to begin with when I think about it.
