Look at this transaction for example:

It overpays 5x on fees (not ideal, but can live with that)... but the issue is it needlessly includes over 60 tiny #utxos in the input, which makes the transaction size almost 30x bigger than it needs to be

So their minor issue of bad fee estimation is exacerbated by their major issue of terrible coin selection, costing them orders of magnitude more in fees
