Hi,
I have a couple of suggestions re promotions:
1. Improve the Drill line. For example, changing the chances of first strikes to first strikes, at the very least for the first level promotion.
2. Many of the unit combat promotions (e.g. shock and cover) work for units attacking and defending. This means they're of better strategic value than the promotions that impart bonuses for terrain which are typically just for defending.
With forests and jungles so predominant now, I feel there's now an over-emphasis on the defensive aspect of conducting warfare. This involves simply blocking approaching stacks by placing units with defensive woodsman promotions in all the forests and jungles. These terrain features already have a 50% defensive bonus! If, however, the promotions were to equally emphasize attacking into the terrain type, then there would be more to the attacking/counterattacking aspect of warfare.
So, with all this in mind I was wondering if the Guerilla, Woodsman, Field, Cold and Warmth promotions should be designed to better emphasize attacking into the terrain types? I think for Woodsman and Guerilla they only get this on level 3.
And an observation on units:
I don't know whether it just depends on which parts of the tech tree one focuses on, but the arrival of swordsmen at 10 strength seemed to dominate proceedings. They were vastly more powerful than any of the other units available at that time - archers, mounted infantry, pikemen - and macemen, their natural counter, were considerably further down the tech tree.
