Enough about AST! How do I use Emergency Tactics?

[Cynfael]

The only thing i feel like it should be changed in this CD is the animation, in my opinion it is too long for an "emergency"

I feel that the emphasis is on "tactics." This is not the ability you hit when someone is literally about to die (Lustrate and Indomitability can be used for that already); you use it to more easily avert an imminent healing emergency.
