I don't know how you plan to solo it but someone said the following on BGG today (sounds like good advice):
A great, sprawling epic. It will take you an age to play it, but it’ll be time well spent. Forget having to learn specialised solo rules. Simply pick a team, jump the turn marker two steps each turn (instead of one) and ignore all cards that reference the other team (discard and draw again).
Yes, thanks. That was about how I wanted to do it. Only take note of neutral enemies (I haven't read the rules yet, so this is a guess) and skip the rest of the other team. I'll check the forums before playing though.
