We have to wait for the personal mag buff to end before we can refresh it. It would be nice to not have to wait especially since it could be badly timed when gigantix or UQ's come around. I also like to feed it right after I get my food buff since they have the same duration and it lets me make sure I don't forget to get the mag buff as well. Because of this I always end up waiting for both to end when I could be actively playing the game instead. This would also help feed the region mags faster since people would be able to do so more often.
