I've just reinstalled and hadn't backed up my addon's, there are 2 battleground addons that i can't remember the names of:
1) This addon provided some buttons that when pressed would announce in chat things like " 5 incoming to mines" "waterworks safe" and similar quick messages.
2) This i think was an addon though may have been a script, this one would announce in chat the number of friendly and enemy healers, melee dps and ranged dps.
