When I started, I had a nasty habit of hopping from perspective to perspective to perspective. I forced myself down to one perspective per chapter, but I still wonder if it's acceptable to do it at all. There are plenty of good authors who never switch and plenty who do, and it seems to me that those who don't do a much better job of character development, and those who do are really more plot focused.
I guess I'm wondering if that's what it boils down to...Is switching perspective killing your character development in the name of plot development? Or are you doomed to character driven plots if you lock the perspective? Is it worth it? Is there some way to get both?
