I also see uneconomical forwards that seem incomprehensible. It seems that fees don't matter so much to real traffic. Only rebalancers seem to set fee limits in routing consistently. Many wallets like Alby appear to blindly send traffic, accepting whatever fees get the transaction to the destination with the most certainty according to their liveness metrics--but real traffic is fine paying higher fees.

This makes some sense, as Joe-Bob buying alligator jerky from Tom's Apocalypse Shack doesn't really care if he's paying 2-3% in lightning fees for the purchase.
