Good job
Let's finish all these pinked-barbarians ^^
You're lucky, the rhenan-legions haven't rebelled themselves, on my campaign, i still have the britain"s one to fight everywhere.. :p
I don't know if you have noticed, but by destroying the archers-fields and some blaksmith in the un-militarised- cities, they will gain more denarii ( not a lot, arround +50/+200 per town), and you will have the money of these buildings to engage some new ones
Another thing i have done is to make the low milita ( some of them are in hiberian's cities) recruitable for some factions ( franks, romans, celics, persians,..).
I decreased their price (14k !) and their statistics ( arround 2att/2def/5 morale, 50 denarii to recruit, 150 unkeep)
This is a good thing to keep order or have low infantry in time of crisis.... but the rebells recruit them a lot if one city fall down.. :p )
