This patch effectively increases the size of the battlefield. Details follow.
Visibility and fire ranges for all units have been reduced by 20%. This makes correct positioning more difficult, but also more rewarding.
Unit move speeds remain the same. Reaching the enemy base isn't any harder.
Firepower, however, has received a boost. The modifier that previously reduced damage to 85% has now been set to 100%, producing a small but visible increase in damage dealt. This should reduce the length of time of engagements, while hopefully not making the game too chaotic.
Good luck, have fun
