I think there is decent argument for changing the card to a simple total of getting 7 wins for the one adept drop. They don't get a flawless or go to the lighthouse or anything but at least they would be certain to get a loot drop from their persistence eventually to keep them coming back for more. If the purpose of the persistence card is to tempt those who can't or won't play trials into the pool of players to get the numbers up then most of those players will quickly get discouraged again after trying it as they win/lose over and over and make little or no progress. Remember that the more people playing the better and it can only help those who are good enough or sweaty enough to go flawless as well as there will be more fodder for them to farm wins on.
