Same thing, today, with something I didn't understand.
Me (elves), and three ennemies against each other. Mordor, Isengard, and the last one Gondor far away from me.
I attacked Isengard, with my full army and Galadriel. Usually, when I'm there, no AI can stop me. In Starcraft 2, we call that the "
death ball". Common in every RTS
But there, halfway, Mordor AI intercepted me. The Necromancer killed Galadriel (!), and Nazguls killed the other heroes (Legolas, Haldir and the other of the main base). With a tide of orcs. Beornings killed the pack of Nazguls but I was really surprised.
Mordor is organized, it's a bad news for Free Peoples.
Bravo !
