I cannot see a reason not to do it, other than mana concerns, which really isn't a concern if you have JOW up. It might seem 'small' said like that, but it could very well mean an extra 50-100 dps. Of course, you would have to time correctly your new AM so that it happens right after a tick while taking into account lag (quartz could be modded to display the lag bar at every tick of AM starting from the 2nd).
