burning crusade cost 30 bucks 8 years ago, it came with a new world, 6 zones filled with over 1000 quests across 2 opposing factions, 7 dungeons(strikes) 5 raids, and 2 new playable races, and it took a year to beat. the dark below costs 20 dollars, no new worlds, no new zones, no new races, one npc who is probably just as hollow as the rest of the tower, 1 strike(unless you are a playstation user), 1 raid, and 3 pvp maps. now if they follow the traditional activision dlc formula as cod(which they probably will) there will be 3 more dlc over the course of the next year with the same amount of content, for a total of 4 strikes(8 for playstation) 12 quests, 4 raids, and probably no new worlds or zones. for a total price of 80 bucks, u will get half of what world of warcrafts burning crusade gave you.
