Hmm. Maybe the AI tries to dispel, but fails often. Or that he doesn't get to try often: For some nations, it does tend to require a bit of deliberate effort to be able to cast a dispel: While Astral-3 and enchantment 5 aren't what I would consider big-ticket items, for many nations, getting that astral 3 tends to require at least some amount of deliberate effort in items or empowerments, which the AI tends not to do.

Also, I, and I suspect, most other human players, are in the habit of ramming hundreds of gems into an enchantment just to make sure it STAYS there, which the AI probably doesn't cope with very well. Although it is funny in MP to ram random amounts of gems with no correlation to importance into enchantments, just to baffle people and force them to waste a ton of their own gems dispelling something you didn't put any gems into, because you intended that casting as dispel-bait anyway.
