Well, I did think we could go with four, given how the classes are now a bit more mixed up and how the introduction of new players would need to wait until "checkpoints". A fifth player could work, but even then they'd have to wait for some time. I can put up an open recruitment once the next checkpoint approaches if it looks like we'd greatly benefit from adding the new member. Four is more or less the optimal size for this module, which is why my search range was set at 3-5.
