What's so bad about forts?

[Rhedd]

Due to their cramped confines and total lack of defenses, they're no better (usually worse) than an open field battle.

The real clencher for me, though, is that unlike a field battle, you always count as being besieged, so if you lose, everyone dies.

No benefits plus insta-death if defeated equals a terrible place to fight.

I do construct them in chokepoints and man them with a few cheap archers. They work nicely for slowing and whittling down an invading enemy.
