What is the single most important thing to be patched?

[Didz]

In both STW and MTW, a player had the capability of out-maneuvering the AI on the Campaign Map with well thought-out chess-like movements of one's Stacks. In this way it was possible to take a Province W/O fighting a battle(s). This capability has been COMPLETELY lost in RTW. I don't recall, specifically, but there is a Sun Tzu quote that directly states the goal is to win a battle w/o actually fighting it.

Perhaps:

'To subdue the enemy's troops without fighting is the supreme excellence.'

or

'Generally the best policy is to attack the enemy's strategy. Next best is to disrupt his alliances by diplomacy. The next in order is to attack the enemy's army in the field, and the worst policy is to attack cities.'
