New amendments just added to the errata:
Late Republican and Early Imperial Rome:
Due to their superior training and self-confidence, Drilled legionaries may elect not to close up when within 8" of enemy, and may continue at their full movement rate. If they charge more than 4" into combat, they will not receive a Close Order bonus.
Early Imperial Rome:
No more than half of all Auxiliary bases may be Archers.
There must be 3+ units of Warriors.
