The Secret World Officer
Why? Well, I ran one set today (5 mummies, 5 ghost-schmeers I'm not looking up the names, OK?) and netted two Condensed Anima out of the ten we got from the missions. CAs cost anywhere from 15K to 35K right now, since you can still fuse them to Nemains; and Nemains are still through the roof (150K-300K). So I think that it makes sense to get in quick MB runs (6 at a time, maybe), swapping out LoMSers so that people get their chance. This wouldn't be forever: I figure that Nemains will crash in a few weeks if not a week, and then so will CAs. But until then, I think that this strategy might not be a bad one.
