You know what would've really made this museum interesting? If these items provided time reductions on training, building and research. Another novel idea would've been increases to attack/movement speed along with corresponding decreases to invaders. Instead we basically get the same tired variations of hp/dps/production. They're ok, but like many things in this game that they hype up they could've been so much more with the slightest bit of outside the box thinking.
The day one blueprints nerf was ridiculous. I get that these are potentially powerful upgrades and Rome wasn't built in a day, but dropping them from the initial 40 blueprints per artifact sold to 15 is a bit extreme. Considering that each level up appears to increase the requirements by 200 each time we're talking 11,000 blueprints to get one boost to level ten.
Then there's another bottleneck with supplies, at least it appears that way. I've never used my dock but I can gather the people who have heavily invested in it are not happy with the changes to it.
Now if we could sell or even gift artifacts within our alliances that may be interesting. I have no use for increased bomber or wall miner damage but an alliance mate may, I'd be fine with giving it to them since I'd only be out a whopping 25 fragments and 15 blueprints. In fact, there should be more to alliances than wars, chats (when they work), and donating troops anyway but that's a topic for another post.
Thus far the best thing I see about this is an improvement to the overall game economy though this will take awhile to become noticeable. The top guys will now be even more unbeatable but I doubt they get raided much anyway. Not too thrilled with the idea of the tired raider and wall miner spam getting more of a boost, yeah, you can build counters to it, but that will take forever.
Please do not apply this to wars, ever. No matter how much the whales wail.
Overall, one can put as much or as little onto this as they'd like, so that's good. It isn't quite the mandatory arms race the university turned out to be. And I'm sure, much like many an anime villain, ''This is not even my final form!''
