Because if it isn't romance, it's a gunfight.Why limit yourself to 'army of two' against the world?-See also: USMC rules of gunfighting.

Actually, dude, even that would be a change from what I keep seeing o.0 
And while I do see your point, non-romantic pair ups of any kind are popular for stories - buddy-cop duos are the first one I can think of, as are 'hero and sidekick' combinations too (Batman and Robin, the Doctor and companion, etc). While it might not be 'tactically sound' from a realism point of view, in terms of storytelling and fiction it's very popular and common to have a non-romantic pair of characters. And it doesn't necessarily need to be super-realistic all the time anyway. 
But that kind of plot doesn't seem to be something popular, or at least easy to find in the 1x1 forum.

This is what I see, from just looking at the titles, and even at the posts - 'X seeking Y, no Z' 
Not anything at all to do with what's being played, what the story is, what the plot is, or anything. And the post is just a list of preferences for 'pairings' rather than any kind of ideas about story, plot, character or anything else. 
Maybe I'm just giving too much thought to what I consider roleplay compared to what someone else does.
