Defensive gameplay and other tactics.

By the way, I recently played on a duel server, and I was playing as humans, although that's not important. The main thing is that my opponent, playing as Dwarves, sent his upgraded lightning tanks (I don't remember their exact name) to my rear and cast the Berserker rune on them, which allows them to attack each nearby enemy without taking damage. In this way, he killed a lot of my units and won. This is how cool the Berserker rune can be used!
