Tactics for the Swamp (Fortress).

Well, if you compare Hydras to other units in a direct confrontation, then yes... but if, for example, there are 20 Hydras in one stack, and 20 Angels in five stacks, then I think the situation will change (in general, in a duel between level 7 units, Monsters crush everyone)... in general, a direct comparison isn't very appropriate; everything should be used at its time and in its place... and you're exaggerating about Goblins and Lizardmen; Fortress has NO useless units; you just need to know how to use everything... and how important it is to have a hero arrive at the beginning with at least one unit; it simplifies the early stage so much that there are no words...
