I'm interested in this, but the poll has closed. I'm not a member of a clan, and probably won't have time to be, so 1v1 is most interesting to me. I also love the idea about Mercs/bondsmen for lone wolves, but this would need to avoid becoming too complex. A way to track their experience/match statistics would effectively become their resume, and they might have to be dealt with differently to a standard player if that is possible.
Heck, perhaps I should just join a clan. I have no dea what kind of commitment (hours per week) is required for this though, hence I haven't looked into it.
