ARR is going to have user created addons so if someone made a deadly boss mods type addon to help out on FFXIV boss fights would you use it?

The addon would do stuff like alert you when the boss is about to use a devastating attack, tell you when something should be stunned, tell you to move ahead of time or if your standing in something bad. Have timers for when bosses special moves become available. Those type of things, all done by analyzing the battle log.
