Charm Animal question

[Shaun421]

Is the Charm Animal line of spells useful at all for a Druid? I haven't done a serious amount of tooling around but it seems that no matter what I charm it breaks in less than 10 seconds. Even green mobs break charm.

I obviously don't expect it to work anywhere close to an enchanter, but does it work at all? I see that Druids get spells that are supposed to buff their pets, but I can't even keep something charmed long enough to finish casting the buff.

What am I missing?
