What about a bid system with commendation points? There will be limits including how much you can use at any given time and week but the idea is to let players use commendations to add to their loot rolls in df or trials before they roll. Item drops and he decides to use 5 commends he has gotten this week to add 10 points to their final roll. If the system rolls 65 for him the result will be 75. Again the system will not be based on commends accumulated so far but starts fresh while keepimg the old total counter and has their limits to not allow players overuse the system even if they farm commends with friends.
