I strongly suggest re-adding Black Uruk to Isengard as a 2,500 point class, and Longbeard to Erebor as a 3,500 point class. These classes once countered the stronger enemy units, but without them their team does not stand a chance.
Black Uruk: Armor: Iron chest, chain legs, iron boots. Resistance 1. Weapon/other: Iron sword (sharp with vote) 5 pork, and the uruk torch.
Longbeard: Armor: Dia. Chest, Iron boots, iron leggings. (helms for legend plus donors) Weapon/other: Sharp 1-2 (voting) diamond pick, 5 pork.
These 2 classes helped balance out maps that needed a counter, considering they where both 10 euro classes that most donors had. They helped balance out maps, and in a way they where heavily relied on to make a map equally fair, at least the classes. With their absence, these maps cannot operate as well as they once did.
