Pre recorded voiceovers for all races/genders that indicate directions, or say things like ‘follow me’.
Emotes that are applicable to battle or that allow you to communicate positives and negatives in smaller groups. /no /cheer /point /beckon etc.
A way to put a ‘beacon’ down like a flare to indicate where people should go. Give it a long range, make it so it doesn’t interact with anything, give it a long cooldown so it can’t be spammed, maybe two or three different colours. It could even have a cool animation like a thrown smoke bomb. /smokeblue /smokered /smokegreen gives you a targeting circle, you click and channel for 1 second or so.
