Any chance we'll see CoC updated so that duo runs of CoC only have two characters [or even, is that a possible change that could be made]? I quite like the change of pace in tactical considerations and character experience that comes from that, so it's a pity to not see it displayed. Furthermore, it's a major RP-buzzkill to enter with two characters, be told your bodies are shifting and changing, and then suddenly have a third person hopping around Perhaps an NPC hireling coming in late to the fun? =O Anyway, be nice if there was an option for such, if it wouldn't be too much of a demand to change. Flip side, other people have noted they favor the 3-character approach as being 'easier'. So I'll note a potentially compelling reason for the change: As others have mentioned, if you want to win Caverns, you tend to want to play it solo. If you're going for a fun experience, you go co-op. Ergo, this would enhance that perspective. Whelp, not like I'm going to not play it or something if the change doesn't happen. In fact, my new addiction is sweetly calling me.. :X
If we're stuck with using three characters I would love it if you could at least alternate who has two and who has one. It sucks that the host has two every time.
