NPC defenses at the end zones

[karlek]

Imagine that a few NPCs are placed out as rear guard around the end-zone, desperately trying to stop the mobs.

Of course the player will get the money, but annoying 1 hp left leaks will be prevented and it would look quite badass. It could also be lore related which NPCs help with the defenses.

The Sentinels preventing the rampaging Fel Corruption from entering their beloved Ashenvale. The Scarlet Crusade hindering the Scourge from leaving Stratholme and kill any civilian humans trying to escape. But, you'll be alone when holding the last stand against the waves of historical armies emerging from the Caverns of Time.
