Discussion about Sylvan (Wood Elves).

Usually, the Sylvan faction forces the enemy to adopt an offensive tactic, as their archers and chaos magic make it impossible for the enemy to defend effectively. The enemy is forced to engage in the Sylvan half of the battlefield, which exposes them to the archers and also costs them a turn to move.
It is rare to force the Sylvan to attack first, as there is no need for it. Therefore, I believe that if you manage to force the Sylvan to attack, you gain a significant advantage.
