Depends on which set you use.

The Overlord's Warband gives you a set bonus for 2H weapons with
Derex, Intex, Strax, 50% speed bonus in towns and pve maps, and a purple halo.

The Warlord's Overband gives you a set bonus for
Darzac, Mantex, Wastax, 75% speed bonus in towns and pve maps, and a light blue halo.

THe Warlord's Prison Band gives you a set bonus with the new
Ok'Tal Molix, Xilom, Casyr, Rysac, Kyraz, Zaryz sets, even more speed bonus in towns and pve maps, and a light blue halo.

If you use these rings over the 3 piece black rings, the set bonus is significantly better.
