Dependence on local units?

[Tolg]

Basically I use 3 different types of armies:

1. Factional armies: Those are my main offensive armies, they fight without any reinforcements till their numbers are so low that I have to withdraw them to my homelands.

2. Regional armies: Their chief purpose is to defend borders at which factional units aren't available. Greek or Celtic armies (because of their huge AOR) sometimes also assist my regional armies when attacking, but even then they stay behind them to prevent the enemy from attacking my rear.

3. Mixed armies: Those armies develop when there aren't enough useful regional troops in an area which I have to protect against powerful enemies. I then use a Factional army for defence, but as I don't use more then one army I can't withdraw and replenish them. Instead I use mercs, locals and even regionals from other areas which makes those armies considerably weaker then the other armies. So weak that they're completely useless in attack (they can't take more then 1 or 2 major battles without needing reinforcements) and that I usually split them into a factional and a regional army once I don't need them anymore.
