May I inquire as to the reasoning behind this strong preference?

A few reasons. First, it's just the convention in tabletop gaming, and what I'm used to--one person at the table, one character. Second, I'd prefer this to be a "small group" game; if everyone is allowed to have two or more active characters, that shoots us past the five-character limit I mentioned when we started. Third, for your character in particular, part of the reason I was comfortable okaying the Xeno ability was because of the balance of him not being able to do anything not directly related to sniping. The abilities are very powerful, but the conflict of him needing to rely on his teammates for everything else--or choose to break his own moral code and suffer the consequences--is interesting. But if you can just switch out to a different character then that's suddenly much less of a drawback--maybe not strictly from a character perspective, but definitely from a player perspective.
