For clarification:

The Mists of Deception/retreat problem will be considered an exploit. Don't script your caster of Mists of Deception to ever retreat or you risk being put on AI.

As far as this applying to all other battle enchantments we'll just take it on a case by case basis. I'll say that as long as you leave your caster in in the battle for 5 rounds it is OK to retreat after that point. If there is a pattern of someone obviously casting battle field wild enchantments on the first turn then immediately running away then I'll address that when the time comes. As long as you respect the compromise 5-round rule (excepting MoD) you shouldn't have to worry about it.
