I agree with patteki on long term material problems, but I know, the team has that on the agenda in one way or another.
to add to my earlier ramblings about increased maintance costs to actually run CLR, ELP and SCA, the production time should also be increased. this would increase the opportunity costs and so keep CM at a reasonable price even when the cost for the construction materials falls significantly.
last but not least, I would like to remind another player of the suggestion of the profile of “trader”. maybe he cares to elaborate, as it would fit nicely with the new szenario (on what I can guess).
