My largest complaint with this event, and the finale was that it was so heavily RNG related on the reward. Completing a epic one time event should not have rewards left to chance. In my opinion it would have been better to give players 1-2 tokens that they could exchange for uniquely skinned Exotic weapons. This removes a few of the issues prevalent with the RNG chest:
1.Players don’t receive anything actually unique to the event that is able to be shown of visually. There is no way to really show a player you finished the event besides linking a accessory.
2.With it being RNG there is a chance you won’t get anything you can actually use, which is a shame that in a finale one-time event you don’t get anything actually useful for your character, it’s a shame.
3,Making it set items, that are possibly account-bound, prevents the event from influencing the economy or prices of items obtained by chance in other dungeons.
