I'm unhappy that they took things away at the dock, even if it isn't cards. Some of the things, sure, take them. But the peace treaty / army combo from the san francisco run was great, now it is an army and some researchers.
As far as the artifacts themselves, I have "crafted" a few dozen of them. None of them even close to worthwhile to start upgrading, or even display in their initial state. It is an RNG crapshoot, and will be very annoying to participate in. Especially given the stinginess of the rewards - attacking one age down is worth no more than 10 shards for a five star, even if they have a maxed defense for the age. In AA, that means minimal rewards from some very tough global ages at a decent medal count, or a strong incentive to drop down in medals and HT raid at the bottom.
