Med factions currently only get one Mebulon DC. Do these accumulate when factions merge or are DCs > 1 lost? For example,
If A and B merge, and neither have used their Mebulon DC, does the resulting faction have two Mebulon DCs?
If A and B merge, and A has used their datacard but B hasn't (or vice versa), does the resulting faction have one Mebulon DC? Does it depend on which direction the merger is in?
Depends - does the Med Neb DC count as a medical DC or a ship DC? Since DCs that don't match the faction type are lost when merging, as per the rules.
And Orph, for your second part, yes it does matter. There was 2 medical factions that merged a little while back. One had used up theirs and the other hadn't. They messed up and the one that had it merged into the one that didn't, and they lost the DC. I guess that would also answer the first part too. So merging will mean that the DC in the faction that is merging will be lost, probably due to the rule above in the faction merging rules.
