In PSO2 Urgents, Xiera was very informational with her voice overs. Allow you to know what you should be doing. Even sometimes it was little late or annoying. It was there to help you focus during a urgent when UI is overwhelm with text info.
Now, Ran in NGS now need to be informational by voice when newer players don't have the time to read or lacking situational awareness. Ran does inform the player by text. But, it is short and could be accidentally ignore when emerging to a area and getting allocated with surroundings.
I believe this would be good for Mining Rig Defense to explain what is going on in this Urgent. Also giving voice warning when a tower rig being damaged or attacked for those who need to be aware. Cause the are focus on something else and not looking at map.
