All this time I've been thinking about timed challenged dungeons instead of normal ones. For example 20 min Gold Medal=Better loot,More Experience, Extra Glimmer. 35 min Silver Medal=Good but not great look, maybe some glimmer. 45 min or more Bronze Medal= Normal Loot, No Extra Bonuses. Also a Timed Challenge Dungeon Ranking Leader Board. Top 5 Highest Scores And Times. That stay the top five for a week get a special reward. Please comment any idea or your thoughts on this be open minded :).
