I find that all my strategy plans are derived from map terrain, map will decide on best troops, heroes and troops walking directions.
Looking for strategy plans derived from PVP strategy and to my suprise the enemy troops and locations only change my tactics plans, the length of planning when faced with enemy is one turn, current list types of enemy troops are only used for next turn choices, both me and enemy may have a totally different army in this spot one turn away and troops on enemy army do not change any of my strategic plans.
