Nemesis + Imprint is head and shoulders above any other method of getting good exalts

And I don't think that should be the case. Natural Drops and prophecies quickly become irrelevant when it comes to farming high-quality exalted items. Probably my largest gripe with this difference is that it invalidates the main process of the game of kill monsters -> get loot, but I also find the process of just running nemesis hoping to get high tier multi exalts, then chasing imprints, to be a pretty unfun system. Certainly not fun enough to be the only practical way to get a decent endgame exalt.
