I say this because the content should get easier naturally with the ilevel raise. I know you want to make it easier for noobies, but all the current veterans had to play through it at it's original difficulty as noobs, why make it easier for the current batch of noobies? One of the things I enjoy most about old content is the ability to return to it later, as a higher geared character and seeing the difference in how much more effective you are than before.
My point is that making old content easier is pointless and serves no purpose. I can understand making REALLY difficult content easier, like Titan EX, but not dungeons, these things are easy already and will get even easier as you gear up. Thoughts?
