Saying something is fine in general just because it works for you is really bad practice. Also, referring to an event where the condititions were different (the D piece was tradeable) is not going to help you prove any point. Both of these arguments are used too often, and don't cary much value. Given the chance for the Orb of Versalmas Cheer being 10%, it's easy to work the probability of not getting it for 30 days on a row. Put otherwise, the probability of getting the other 90% 30 times in a row. 0.930 = 4.23% A little over 4% might seem a marginal, but given the amount of characters aiming for an event item, I'd say a significant amount of people will be dissapointed at the end of this event. Even if you're doing the event on 2 characters consistantly for 30 days you have a 2% chance of not getting the final reward. I'd say someone doing that pretty much desirves the reward already. I don't see why the hardest piece should be the untradeable one, or even why there's an untradeable piece to being with.
