Track group and solo Elo separately. You keep talking about adding a set modifier, but that has obvious issues. You can not predict who sucks the same (or even more) when grouped up. Pushing group Elo manually would introduce new problems, specifically: unduly punishing bad players by asking them to carry unrealistically hard. Tracking group Elo would automatically adjust for every player's group play (in)ability.
Track chassis Elo separately. Seeding issues were mentioned for this. One solution would be using MWO-specific battle values (i.e. averaged Elo values for each chassis -- already tracked) to help with initial seeding and re-seeding of chassis Elo. Again, no manual adjustments, just working with heuristics based on Elo.
There are many issues with both of those, though.
Group/solo Elo: not only do you have a LOT of variables to worry about, you also have to consider that some people group differently with different groups. For instance, when I am grouped with my normal lance, I am going to do quite well, but if it is not a practice night I often find myself grouping with random people from my unit that I generally have never played with before. Would I have the same group Elo? What if I did good with the three people I initially group up with, and then a fourth player comes in and joins the group and we start doing horribly? Since we are doing horribly, one of the initial 3 drops out, so we are back down to a group of four and start really clicking. Obviously, the issue was between the fourth player and the one that dropped out, or was it? Maybe it just took the fourth player a little while to shake the rust off individually, and now that he has, we would have done well even if the other person had stayed. WAY too many things going on...
Chassis Elo: much like Roland's idea of "value by popularity" in another thread, I am not a fan of doing Elo based upon mech chassis, since there are way too many things deciding how well you do within a chassis, especially loadout. The Clan Omnipod system makes that even more difficult. I think a much better way would be to have an adjustment to your Elo (or just base "class" balancing upon this number instead of straight weight), based upon the combined Battle Value of all components equipped on your mech. This would give a very easily calculated, but highly accurate, number to balance with.
