So, with 4 expansions being released, we've seen two ways of approaching the new continents. In the first two expansions (TBC and WotLK), you were a soldier in a large-scale invasion. We went to a lot of different bases (horde or alliance) and helped the encampments out in their missions of controlling the area. I still remember setting my foot in Valiance Landing and after the first quests walked up on the plains and saw a huge stronghold, being Warsong Hold. This already made me anticipate playing a character from the other side. I also fondly remember walking into Honor Hold, Sylvanaar and Allerian stronghold for the first time back in TBC.
With Cataclysm and Mists of Pandaria, we engage with the new world in a different way. We are now special agents, going into faction-neutral bases and receiving our orders there. We help out the locals the way we can, and we are in the new world way ahead of our own factions. While this makes the continent perhaps more mysterious and "unexplored", I think I prefer the way of TBC and WotLK, where our specific factions are heavily involved in the invasion.
My hope is that WoD will reintroduce this concept, as the horde goes with the Frostwolves and the alliance supports the Draenei. What do you think, what style do you most prefer?
