Hi,
I’d like to suggest a leaf from GW2’s book here: mobs in the word (like bison) that don’t have any particular antipathy for the player should have yellow name-tags, not red.
Red should be for those aggressive to the player. It’s a color I typically watch out for, and it’s confusing sometimes when it turns out to be a harmless animal.
Please, if it’s not too much work, give animals yellow name tags until they’re attacked or attacking.
