The Company of Dwarves gives you a more varied group of heroes than the others, including at least one of each of the four types of characters. Ori is an enchanter who can increase the damage of allies, shield himself, mark nearby enemies, and do high damage in an area to those marked enemies. Gloin is a warrior with a lot of damage based moves, a stun, and a defensive move that increases resistance and sets enemies on fire that hit him. Kili is a ranged striker that can reveal stealthed enemies, tumble to remove negative effects on him, and can slow and stun enemies with his arrows. Nori is a tactician who can increase the damage of allies, raise the defense of allied structures, and can teleport to and damage enemy structures. Thorin is a warrior with lower health and higher attack who is able to increase his movement and attack speed, critical chance, shield himself while reducing enemy attack speed, and can do a powerful attack with a chance to crit. The Guardians of Middle Earth online community is mostly dead but there are still occasionally groups of people getting games together, due to that and the high price this DLC is likely not going to be worth it unless you have a group of friends actively playing the game or you find people that are still willing to set games up. This pack of heroes does give you the most variety, including heroes with very different abilities and of all types.
