Soon Dion will come and start saying that everything is fine, because now units have a lot of different ways to attack, so there will be a lot of tactics on such a map...
But I still don't quite agree; here are my arguments:
1. Thick units are weakened in tactical movement (natural obstacles and those placed by the enemy will make them stand still)...
2. Mass damage spells rule without restraint...
3. The melee starts immediately, and it is impossible to carry out a retreat maneuver from it - because there is simply nowhere to go...
My opinion is clear: make the map bigger, at least always as big as it is when defending a castle...
