I have to agree with you. I find it extremely boring and tedious waiting for NMs to spawn only to have it stolen away by someone who's faster at mashing that provoke macro than you. At least with the forced spawn NMs you don't need to worry about revolving your schedule around a single spawn for a low drop rate item. This would also drive down the prices on the items that these creatures drop, providing they don't get switched to Ra/Ex.
