This is no longer a story about how war is bad, both sides are doing bad things and the pandaren are the victims in the middle, this is a one sided issue of them almost trying to make the story into the old warcraft days of good humans vs bad orcs, and ruining the story in the process.
This is how I read it.
The meta-narrative of recent events is that Blizzard wants to vanquish hatred, fear, anger etc (the Sha) which cause divisions between players. Garrosh will become the representative of divisiveness and we'll all co-operate to defeat him. The war between the Alliance and Horde players will end. All auction houses will become "neutral" and the economy will become unified. The new enemy will become an outside force. Blizzard will continue to remove things that cause anger and distrust between players. Personal, secret loot drops will be used in dungeons as well as LFR. This will help quiet dookers (griefers) with meters and bad attitudes. Co-operation will be a win-win situation. In the short-term there is going to be some horror. Dalaran is on the move. The fall of Theramore is going to have to be avenged. I think Blizzard would like to redo Silvermoon, so enjoy it while you can.
Considering our War sparked the rise of the Sha, the Zandalari are waging war against everyone, the cornerstone of Mogu culture was war and domination, and that Garrosh is likely going to be corrupt by a Sha in the end...
yeah War is a big part of the storyline. I wouldn't call it a villain like Kil'jaedan, Arthas, Deathwing, and Azshara are, though.
You'd think the message that 'war, violence, hatred and doubt cause these things to manifest, we need to find another way so they don't grow in wow', it instead became a case of 'HaHA, i have defeated the sha, what new thing shall my I kill?'
The differences they are making between Garrosh and Varian is almost cartoonish. I like what they are doing with Varian, I just don't think they need to make Garrosh so cut throat and brutal to show the contrast. I really don't see how any Horde person could want to follow Garrosh, He's just too far off out in left field
