For a Dungeon article, I'm sure the switch has not been too much of a hassle. When I'm writing a module spanning 4 APLs, then you're talking about a lot of stat blocks. In the current LG stat block format, the save DCs are pre-figured - add spell level plus a number. And while I agree taking a work load off of DMs is important, I have yet to see a tool I can readily get my hands on that is completely LG legal which spits out correctly formatted stat blocks. Usually such tools only have OGL material. Hence, I have to manually type everything in - anything that increases MY workload without a clear across the board benefit I'm going to avoid.
