Sanctuary Onslaught - what exactly is the point of this place other than farming Khora?

after getting Khora is there a reason to this place? from what I can see elite version doesn't have any Khora parts and the rewards have such a low drop chance might as well do endless fissures instead of hoping for a radiant relic drop.

it doesn't give anything better like a lot of credits or drops, maybe some Endo but no one farms pure Endo, they all use Ayatan Treasures for obvious reasons. so overall maybe just apart from leveling gear (isn't hydron just better? what about those exp boost areas on plants, aren't they also better than Onslaught?)

and let's not forget the "I'm gonna block the ability you are spamming because I'm an asshole" part.

I feel as if DE just forget about Sanctuary Onslaught at some point and never bothered to make it interesting or useful, hell even that crap game Index at the very least gives you supply of credits. now that I think about it, farming credits anywhere else seems pointless so in a way Index is too good.
