That orc gate guards are aggro to anyone below I believe level 30. That orcs lead other orcs to gates and have them aggro level 51 orcs on the people who are trying to raid.

And then necros and other douchebags summon mobs and scourge them with level 55 uncureable spellcrafted crimson scourge. They also summon mobs that also assist orcs (giants/goblins/etc.) who assist throughout.

I just don't see how Immortals cannot see this while I lived it for a month and a half.
