These weapons are good for alt classes, or those that don't quite yet have the extreme, savage, ultimate, or tomestone weapons. Afaik the weapons from PotD, were no different. Not to mention people levelling in heaven on high, or doing heaven on high alongside their MSQ, can immediately get a 365 weapon upon hitting 70 in some cases.

Besides, I hardly see an issue given getting aetherpool is much easier in Heaven on High than it was for PotD.
