Game Mechanics: Mage Pet Spells

[Splorf22]

I played a mage on live, and I remember that all of the pets would cast every 6 seconds except the air stun, which was 12. This matches lucy precisely:

So they should be casting those spells very frequently. And in fact I remember that magicians were concerned that their pets were wasting time casting these spells rather than meleeing and GZ was sure that it was not a problem. I recently bought a Magician and my feeling was that the pets were not casting nearly enough. So I went out to DL, maloed some green/lb cons and sicced my pet on them. I was carefully watching for resists, but between the low level of the mobs, malo, and getting lucky on the level of the pets every spell landed.

Now my (possibly faulty) memory is that the pets would cast every 12/6 seconds like clockwork. But even if it was somewhat random, I am 100% sure that the earth pet rooted more than once a minute. This is not only a pretty big issue for mages, but I'm wondering whether dragons are casting their aoes frequently enough.
