I think it would be pretty epic, if suddenly, out of nowhere, without any warning, in the middle of an ordinary round of battle, filled with hordes of players something very unusual would happen.
First, a slight shatter to the ground which rapidly evolves into an earthquake. Everyone stops fighting in an instant. A cloud of dust, spitting out of the very center of the ground everybody stands on, bewatched in total awe by hundreds of people. Nobody knows whether to be afraid or amazed. And then without any chance of taking a guess what to come, a giant undead knight, the size of a castle arises from the dirt. And when he finally got his old bones standing straight he tells you, once his sword eats through your flesh, a heirloom once given to you then belongs to him.
A moment of shock. At once all the disputes between swords, arrows and lances and their wielders are gone. Only with the combined force of cavalry, infantry and ranged this day can be survived. All the things you have worked hard for are at stake and you have to fight like it would be your last.
This was completely off topic. But so are all anti-archer threads right now anyway.
