What I want to say is that many battles have been played, but I didn't do any calculations; instead, I took into account and remembered the maximum capabilities of various Castles, purely practically and subconsciously.

I remember cases when, on the 3rd week, without Maschast, Slava, and Tactics, a Fortress hero could defeat up to 100 Monks and up to 100 Sorcerers, having what, at first glance, seemed like an unremarkable 3rd-level creature (Group of Dragonflies).

I would highlight 2 Castles that stand out from others in terms of creature survivability:
1. Fortress;
2. Rampart.

Although the 3 Heroes (yes, I'm not kidding), who studied physics and gave us PhysMig, rank Rampart as number 1 in terms of Health.

But my experience (I admit, it's a subjective point of view) puts Fortress in 1st place in terms of Health. I explain this by Tazar's natural ability.

I see a drawback in Fortress in the lack of a strong starting army, with which I don't always risk breaking through to the secondary resource node on the 1st week.
Of course, I might get lucky and receive enough troops from 2 Heroes. But many times, I've been defeated by 30+ Gnolls and 9 Lizards at the start...

By the way, has anyone noticed the fact that in battles with strong opponents, the odds are usually, to put it mildly, not very good?
I have repeatedly noticed this pattern in my games, but how about you?
Please share your opinion on this.
