[Would cult be better if you couldn't summon Nar'sie?]

Cult rounds have a lot of cool flavour and mechanics, but it just feels like it comes down to that not mattering very much - you just nab a few greytiders, then nuke the station. Without the summoning, cultists would be forced to play a little more intelligently, and that Lovecraft feel of detective against cultist would be better preserved. What do you guys think?
