Classic WoW world buff timers and pre buff drop warnings so you never miss a buff.
Novaspark-Arugal for any questions.

What it does
Warning msgs in chat window, middle of the screen, and guild chat.
Warnings for each channel and time left can be turned on and off with /wb config.
Current warning times are 30/15/10/5/1 minutes left until buff reset.
Guild msgs are configured so only 1 person online at a time will send warning msgs to avoid spam.
Guild chat is notified and timer reset if a buff NPC is killed infront of a member with the addon installed (mind control reset).
Any guild member can type !wb in guild chat to display all timers.
