Auto chat system! How should I use it to notify or help in group battles?

Something I noticed that their is an option to use auto tigger chat that is situational. Something that can be use to strategize group combat engagements. I guess what I am asking is what are some of your communication strategies you may use to convey group cohesiveness and cooperation?

You can use it to list E-Codes, when your HP is getting low, or when you get KOed, just DO NOT USE CUT-INS ON THESE AUTOCHAT TRIGGERS
