DC Universe Online, you'll be disappointed. If you're hoping for a better system of player rewards and more challenging encounters, you'll be quite pleased. Game Update 18 ushers in several changes to the game's challenges, alerts, and duos, providing players with both a smoother set of progression content and a more unified system of rewards.
Aside from reorganizing several pieces of group content into clearer progression tiers, the update unifies reward currencies into Marks of Triumph. Reward items are all purchased via Marks of Triumph, with higher-tier items requiring a correspondingly larger number of Marks. Players will also receive a weekly award box the first time they clear a Tier 1 through 3 challenge within a week; these award boxes contain both Marks of Triumph and a random level-appropriate item. For more details on the particulars of these revisions, take a look at the full update list, or just log in and start playing.
