The atmosphere is pretty heated. But I don't understand why.
With the rebalance, everyone complains that it is sent in small portions. Now the museum is being changed in a rapid bang, that doesn't fit either?! What would be the right pace for changes?
I would even be in favor of activating the postponed Sitrep 1 at the same time. Then we can start again with a logical calculation and its effects will also be taken into account in the ongoing rebalance.
Apparently many (all?) agree that they don't want to re-craft. Then it shouldn't bother you that it's theoretically possible, because nobody will use it anyway ;-)
Maybe the community will even find new agreements, similar to esh
Then everyone can agree before the battle to only use artifacts that match the old pattern (max. 2 lines).
Your museums aren't getting any worse. No one takes away artifacts. No lines will be zeroed.
Well-crafted museums will continue to provide high percentages; just no longer the highest possible percentages of a benefit line.
The museum has always been in a state of transition. For example, from heavy tanks to helicopters to mortars. From transporters to fighters to bombers.
Each time we had to craft new artifacts. Now we have to do it again. It doesn't matter whether it's due to a change in the “meta” or a new set of rules.
