Actually, certain aoes are harder to avoid from range than close up. This is true with the front cone types like from Keeper of Halidom in Wanderer's Palace. If you're close, and the cone aims for you, you have less distance to run to be out of it, but if you're far, you have a ton of distance to cover to get out.
I see RDPS get hit by these types much more in PUGs than MDPS. I myself get hit by these more often on my BRD than on my DRG.
