Their purpose is simple, kick out the orcs from Swamp of Sorrows. Here enters the Old School part (I'm doing on the Horde side).
The mid field battle is phased. During phase one, the field is full of human footmen vs orc warriors with clerics, peasants around on side and peons on the other. There is even a quest called "Orcs and Humans".
Phase two, the orcs called the ogres to support them, the humans counter attack with knights. This is so Warcraft II, the quest is even called "Tides of Darkeness". Also, human mages and orc warlocks are opening portals all over the place.
Unfortunally, there is a "honoring the dead" quest that is heavily bugged, so it will take some time until I check what comes next.
