While it might be true that other stuff you fight give some better augs, that doesn't mean these should be boosted. You need to keep in mind that while SSRA named are a bit easier, and drop better augs, theirs also the chance that they will drop nothing at all. Also, they only drop 1 item at a time. The epic mobs on the other hand will always drop 6 epic 1.5 pieces, as well as 2 augments, guaranteed. See my point?
They only drop 1. And it's more or less crap, may as well make it lower chance of dropping and better, than never used.
Even the underbulks are dropping better augs at an alarming high rate, http://thehiddenforest.dyndns.org/npc.php?id=157028, have more HP, too, and respawn a whole lot faster than the namers for epics. These don't compare to ssra basement augs, but still...
The named in ssra basement are 50% chance of 1 of a small handful of REALLY good augs: http://thehiddenforest.dyndns.org/npc.php?id=162156, and the mobs that drop it have 1/3rd the HP, respawn faster, even if it's only a ~15% chance of it spawning, it's only 12 minutes, and there's quite a few named skeletons in the basement you can cycle at the same time, increasing % chance of getting the better augs. I mean, I see you're still wearing ssra augs in a few places, with tier 3 sleepers gear being farmed, makes the augs of ssra basement seem a bit too good.

That's my opinion, at least.
