Let's take a deep breath and think about it for a second.
Before the merge, we built 4 mine shafts, the rainbow bridge, Lerena bridge, the one between Greater and Lesser Aradoth, and a multitude of work stations and shops in the field ...
ALL, without a huge vault.
Now, after merge, we were helped out in rebuilding our lost holdings by the gift of a large vault.
Did you forget what you did before? Or the techiniques you used to accomplish those mighty feats? Or the fact that now, we have specialized cargo disks, that can hold double what we used to. Even my tarbash holds 10500 bulk. And you still get road bonus with it attached.
So turn on the "way back" machine, go back in time and remember how ya did it before. Even with the vaults returned back to pre-merge stats, we STILL have it better than before.
To have accomplisment, you must have challenge and sacrifice and effort. Anything else is mindless, trivial, and boring. I thought you didn't want to be bored?
