I can only second what Teraswaerto said. Playing with % provinces victory conditions benefits astral and air nations greatly. Not many people pay a great deal of attention to PD, and sometimes they even have all their units sitting in forts without using them for patrolling and the fort defenders can be defeated easily. That works if you want to protect your troops, but AFAIK provinces where you are just sieging the fort count towards your province count just the same...
