What are ppl using for this? I know azor recommends timetodie but its out of date... Weak auras as a substitute I guess?
The math that timetodie, etc, use has not changed. The API they use have not changed. Just load it anyway.
i use tellmewhen addon because it can track internal cooldown and proc as well, but, it isn't hard to check the time left on stampede on your action bar.
