I think people somewhat overestimate the gear they'll get from A1; after all, 90% of the time you're still going to be getting the same gear as before. 10% of the time you'll get ILVL 62/63, which isn't bad, but then you still have to get that gear to roll 'rare' and then you still have to get that rare to roll well. The chance is there, absolutely, but I wouldn't expect a lot to come of it on an individual basis at least.
I think I'll stick to Azmodan runs although I'll probably be more thorough about hunting down rare mobs once I get my 5 NV rather than restarting.
