Hmm... it's a pity that you can only test the army here; you need to take everything into account: magic from the castle and War Machines from the castle, and Special Bonuses - like the Temple of Valhalla in the Stronghold.
And then we'll see that in almost all battles, there's no equal opponent for the Rampart and Tower.
RAMPART.
Only the Dungeon and Conflux can compare with it.
I understand... but for all this, there are simple maps, tournaments...
in this map, it checks only the strength of the army in its pure form - that's the point! you can also improve your Combat skill here...
as for the AI, I agree, it really slows things down (for example, I can win with an Inferno army against a Tower army)... try it (one of the most exciting battles)
therefore, it's better to play against a Player, not a simple AI...
