It would be really nice if we could disable seeing and hearing the rank-up/level-up animation and sounds for levelling characters or ranking-up skills/learning recipes, etc. It’s kind of annoying when people are insta-80-ing their characters near the bank or learning a ton of recipes near the crafting stations, etc. On its own, it wouldn’t be annoying, but it happens often enough and with people usually sitting there for minutes ranking up something, it starts to get obnoxious.
Perhaps a checkbox in options that would allow us to do so would be an easy way to fix the issue.
