First, I would like to thank Anet for giving us a reason to repeat CM content! This is the most excited change to raids we've had this year! (Only change, but that's beside the point. )
As for the trophy shipments for gaeting crystals and mag shards. Seems like a cool update, but not yet sure if it's more profitable than infusions. The only thing I want to ask about, is why not do the same for Insights and Divinations? Right now, once you finish your legendary armor sets and ring, there really isn't any use for insights/divinations. I suggest doing the same thing with them for trophy shipments and some reasonable rate as well. that way we can at the very least use the currency somehow. At 25 of them a week max, it really only takes about 24 weeks total to amass enough for 3 full sets of armor and the ring, then they are collecting dust in your bank. I have friends who have 500+ extra insights just lying around at this point due to raiding each week.
Some people might say you can get more asended armor, but 2 things on that. 1. Legendary armory and 2. if you're full clearing raids, you already have more ascended armor than you know what to do with.
