When people play other games, it's as if they're getting revelations that TBC and onward is so different or that it's a WOW TBC Gold different flavor, something more or less the same as retail or other games: it's all the same things and tools, but different grouping and transportationtools, and also different XP bars.
After playing Classic WoW, and then seeing the work that Blizzard put into creating honey-to-do tasks to keep people playing Burning Crusade, with rep farming and heroic Dungeon grinds, it was obvious for me that this game cheap WOW Classic TBC Gold is a hamsterwheel. This wasn't a misgiving of Activision they were all greedy and they needed sub goals.
