Um... The idea of going flawless is getting 9 wins and 0 losses. Passage coins can allow you to get the same rewards for 7 wins and 1 loss, which isn't really going flawless. In the long run, you purchasing gear obtainable from the lighthouse. I don't have a problem with passage coins because you receive them from losing (unless you somewhat decide to go 'Passage coin farming'. Purchasing for items that enhance your success in gameplay shouldn't be a thing. Emotes don't affect gameplay, only the appearance. Purchasing heavy synths, passage coins, engrams or money shouldn't be a thing. In my opinion at least :D
