Heh no. I'm quite happy to see the days of invisible tanks due to gear swap macro spam end. Class swapping mid battle would suck because of the cool down after changing so it isn't like you could quick swap to WHM to cure the tank and go back to BLM. Before anyone says it...they would not ever reduce or eliminate that cool down either. You wouldn't see many full time healers that way. Everyone would be expected to have certain jobs leveled solely for hot swapping.
