I think this comic needs to tell its stories over a longer period to build some impetus and leave room for character development instead of the supporting cast delivering a couple of, 'Aye captains' like the supporting cast of Enterprise.
But... they are mostly retelling old episodes, so to pad them out to three issues per adventure would probably bring just as much criticism from other fans saying that duologies would be sufficient to tell those stories. In fact. I'm sure that would happen. "Filler!" they would scream.
In any case, many of the episodes of TOS do
have the supporting cast saying little more that "Aye captain".
Three issues might have helped with the recent original tale, "Vulcan's Vengeance", but then that would wreck the pattern for the next omnibus reprint.
