Tactics for Dungeon.

Tactics for Dungeon... There were a lot of words, I read the whole thread, but I didn't really see the main point anywhere. Dungeon is the strongest faction for siege.

Dungeon is definitely one of the strongest castles, but everything you wrote above is just theory; in practice, it all depends on the situation, skill, and strategy. If you play very poorly against strong players, all your castles will seem weak, while your opponent's will seem the strongest. Each castle has its own advantages and disadvantages. For siege, the best castle is any, but you need to understand the game and have more troops, better magic, and higher stats for your hero. Everything else is not critical.
